Minutes:

Technical program: The meeting began at 8:00 a.m. on Thursday, July 26 with opening remarks by Paul Rasmussen, Director of the Utah Agricultural Experiment Station. Walt Stroup gave a three part presentation on generalized linear mixed models in agriculture and their analysis using SAS. The morning session presentations were entitled "GLMM's in agriculture and an introduction to PROC GLIMMIX" and "GLIMMIX: Applications, examples and experiences." The third part of his presentation entitled "Unresolved GLIMMIX issues and new features in SAS Version 9.2" was presented as the first afternoon session. The final session of the afternoon featured a group discussion of generalized linear models in service courses. The session began with short presentations by Ted Bailey, Ed Gbur and Edzard Van Santen.

On Friday morning Dan Schmoldt was introduced as the new CSREES representative replacing Larry Miller who retired. Prior to a slide presentation about the organizational structure of CREES within the USDA and its partnership with universities, he responded to the previous day's discussion about statistical involvement in science and education. He encouraged participants to serve on grant review committees for entities like NSF and AES. He noted budget issues and the potential impact of the in-progress farm bill on CREES organization and funding priorities. As he looks to the future, he sees several research areas that are ripe for increased statistical involvement including bioenergy, specialty crops, plant breeding/genetics, precision agriculture, invasive species, and establishment of log-term agro-ecological research sites.

Dan's presentation was followed by a group discussion about the linear models and spatial workshops. Discussion centered on whether or not the linear models workshop needed to be updated in include more material on mixed models and generalized linear mixed models. Rob Tempelman said that the animal science societies might be interested again. Entomology would likely be receptive to GLIMMIX modifications dealing with count data. It was generally agreed that the workshop should be updated both in terms of using GLIMMIX and in including material on generalized linear models. Rob, Bruce Craig and Linda Young expressed an interest in working on the update, including modifications to include more material on non-normal responses.

Business meeting: The business meeting was held Friday, July 27 immediately after the first session. Ed Gbur presided. Mark Hinds and Susan Durham were thanked for providing an enjoyable meeting. The following items were discussed.

(1) Next year's meeting will be held the Ohio State OARDC in Wooster, Ohio on July 21-22. The local arrangements chair will be Bert Bishop and program chair will be Kevin McCarter. Discussion of the 2008 program centered on whether or not it should include sessions on varied topics related to all project objectives; i.e., (i) continuing research in mixed models, (ii) continuing work in spatial statistics, (iii) new technologies, e.g., PLS and remote sensing applications, and (iv) incorporating GLIMMIX into the MIXED workshop and revising the content. The 2009 meeting will be in College Station, Texas hosted by Sara Duke.

(2) Project members were reminded to send their contributions for the accomplishment, output and impact sections of the annual report to Ed (egbur@uark.edu) as soon as possible. The reporting period for this years annual report is October 1, 2006 through September 30, 2007. The reporting period coincides with the Federal fiscal year. The target completion date for the report is the end of August.

(3) People who volunteered to contact various societies about workshops reported on their success. Sara Duke approached the Society for Range Management. Although they expressed interest, nothing was finalized. She will try again. Walt Stroup was unsuccessful with the Horticulture Society. Initially there was strong interest but it waned in the face of details such as registration fees to cover presenters' expenses. In his opinion, they need something more basic than the mixed model or spatial workshops. Rob Tempelman will try Animal Science again. Larry Douglass had agreed to approach the Entomological Society, but he retired and was not at this meeting to report. Linda Young said she would contact the society to determine whether or not they are interested in mixed and/or spatial workshops. Mary Christman had expected to be in contact with the Wildlife Society but did not attend their annual meeting this year. She will approach them this year, although she anticipates their interest level may be low due to the predominance of non-experimental approaches in wildlife studies.

Sara Duke raised the question of whether or not we can give CEU credit for our workshops. It is unlikely that we will be able to charge more than needed to recover workshop materials and presenters' travel costs. She will investigate what would be required and will report to the group at next years meeting.

Ed asked whether the spatial workshop is not as popular as the mixed workshop or whether we need to push it harder. He noted that some scientists think spatial statistics is about making maps, not statistical analyses. Linda thought that interest in spatial modeling might be strongest in ANOVA-like contexts. Mary noted that we statisticians focus on incorporating spatial covariance in modeling with less emphasis on the statistical component in mapping.

In response to a question about what had happened with the project's precision agriculture efforts, Mark Hinds commented that commercial solutions are now available and may be all that users feel is needed.

(4) As the Technical Editor for Crop Science, Don Bullock is soliciting papers to address statistical problems faced by his readers. He envisions a paper, or possibly a series of papers, that outline the transitions from GLM to MIXED to GENMOD/GLIMMIX. He inquired whether or not project members would be interested in writing such papers as a coherent set. Ed noted that our production of these sorts of papers qualifies as continuing education activities under the project. It was agreed that this type of papers have a reach far beyond that of a workshop. Since the meeting, interested project members have begun to sort out responsibilities for preparing a series of manuscripts.

The meeting adjourned at approximately 10:20 a.m.

Accomplishments

Statisticians who consult and do research in an Agricultural Experiment Station environment enable land grant institutions to perform their agricultural research missions more effectively and efficiently than would otherwise be possible. However, most stations have at most one or two professional statisticians who are not, and can not be expected to be, experts in every area of statistics. This multi-state committee brings together statisticians to work cooperatively to determine the best current approaches to common statistical problems and to help guide future directions of sound statistical practice. In addition to group outputs such as workshops, it serves as a resource for its members and a sounding board for new ideas in their applied statistical research.

Impact Statements

1. In addition to group outputs such as workshops and the planned series of mixed model methods papers, the project serves as a resource for its members and a sounding board for new ideas in their applied statistical research. As a result, all members are able to provide more effective assistance to agricultural researchers addressing national research priorities than they would without NCCC-170.
2. The project&lsquo;s spatial workshop presentation at the joint annual meeting of the American Society of Agronomy, Crop Science Society of America and Soil Science Society of America adds another group to the list of subject matter disciplines to whom it has been presented. Project members have begun to offer workshops to their local clientele, the first such offering being to a group of faculty and graduate students in Arkansas. The spatial workshop educates attendees in the fundamental statistical concepts associated with the modeling and analysis of data having a spatial component in a wide variety of situations. The workshop dispels the notion that spatial statistics is the same as GIS map-making.

Technical program:

The meeting began at 9:00 am on Monday, July 21, 2008, with opening remarks by Dave Benfield, OARDC Associate Director. The technical program consisted of the following presentations. Group discussion followed each presentation.

John Stevens. Recent software tools for preprocessing mass spectrometry data.

Bruce Craig. Introduction to partial least squares.

Mark West. Evaluating PROC GLIMMIX for fitting a binomial model with random effects: Transformation and power issues.

Rob Tempelman. Power analysis for research conducted at commercial dairy farms.

Mary Christman. Estimating total Abundance (N) in depletion experiments.

Business meeting:

The business meeting began at 9:10 am on Tuesday, July 22, 2008. Ed Gbur presided. Kevin McCarter, Bert Bishop and Larry Madden were thanked for organizing a productive and enjoyable meeting. Ed noted that Bert is retiring and that the group will miss his participation but that he should follow the example set by Larry Douglass and feel free to attend future meetings. The following items were discussed:

(1) The status of the reorganization of the USDA is largely unknown.

(2) The group considered whether or not to make the technical presentations available to participants and, if so, in what form (i.e., emailed directly to participants or posted to the NCCC-170 website). Security limiting public availability for material available on the website is a concern. It was decided to add a password protected page to the project website to which speakers could voluntarily submit their presentations.

(3) Photos taken during the meeting will be posted on the website unless speakers notify Ed otherwise.

(4) The 2009 meeting will be held in College Station, TX, at the USDA facility and hosted by Sara Duke. The date is tentatively set for sometime during the week of July 20-24. Sara will check on the availability of the facility. Mary Christman volunteered to serve as program chair.

(5) Possible locations were discussed for the 2010 meeting. Rich Alldredge tentatively agreed to host the meeting in Washington. Meeting dates would be coordinated with the Joint Statistics Meetings in Vancouver.

(6) The annual report is due shortly after the annual meeting. Participants need to send Ed (egbur@uark.edu) accountings of all activities (workshops, papers, presentations, teaching related, etc.) from October 1, 2007 to September 30, 2008 (or since last years report) that are related to or inspired by their participation in NCCC-170 as soon as possible.

(7) This years annual report will serve as a summary of activities for the past three years for the projects mid-term review. The group reviewed last year's report and determined appropriate revisions of the review. Specific Goals (1), (3), (4), and (5) are ongoing. Goal (2) has been accomplished and no further work is needed. The series of papers on transitions from general linear models (GLM and MIXED procedures in SAS) to generalized linear models (GLIMMIX procedure in SAS) which are currently in development for submission to a peer-reviewed journal (e.g., Agronomy Journal) will be added to Specific Goals.

For the Impact Nugget document, an item will be added to reflect the efforts of project members in organizing a Biometry Section in the Agronomy Society. Under Impacts, self-training (broadening expertise) will be added as a third point. Under Research Needs, the second bullet will be deleted, and an item addressing emerging technologies (e.g., precision agriculture, various "omics" research) will be added, as will an item addressing the development of software tools in conjunction with the paper series.

Ed will draft the mid-term report and send it to group members for review. He will need quick turnaround.

(8) The deadline for drafts of papers for Agronomy Journal is November 15, 2008. Drafts will be sent to group members with the understanding that they are not to be distributed outside the group and that comments will be needed quickly. Reviewers should consider overlap and consistency of level among the papers.

The group thanked Ed for his leadership and, especially, report preparation.

Announcements:
(1) Mary Christman reminded the group about the Workshop on Environmetrics to be held October 22-24, 2008, at NCAR, Boulder, CO (http://www.stat.purdue.edu/envr/).

(2) Larry Madden distributed a position announcement for Berts replacement at OARDC.

The meeting adjourned at approximately 10:30 am.

Impact Statements

1. NCCC-170 fosters research to identify and develop statistical methodology applicable to agricultural research and provides a forum for sharing and educating both statisticians and subject-matter scientists in the agricultural, environmental and natural sciences. As a result, all members are able to provide more effective assistance to agricultural researchers addressing national research priorities than they would without NCCC-170.
2. Several members of NCCC-170 are also members of the American Society of Agronomy and its sister societies (Crop Science Society of America and Soil Science Society of America). Within the ASA, these members have been instrumental in the development of a new division devoted to the topics of biometry and statistics in the Tri-Societies. The goal of the Biometry Division is to provide a forum for members interested in statistics and experimental design from the research and/or teaching points of view. The Division will serve as a resource and provide training for the larger tri-societies by sponsoring symposia and workshops on statistical techniques and experimental design at the national and regional meetings. It will also solicit review and methodology manuscripts for the society journals.

Technical program:

The meeting began at 8:30 am on Thursday, July 23, 2009, with opening remarks by Dan Upchurch, Southern Plains Area Director.

The morning session and working lunch were devoted to presentation and discussion of the drafts of the GLIMMIX papers.

Mary Christman and Ed Gbur -- Introductory paper

Linda Young and Kevin McCarter -- Repeated measures in space and time

Kevin McCarter and Walt Stroup -- Power and sample size calculations


Prior to the actual presentations, it was agreed that each of the drafts was already much too long for a journal article. Discussion turned to the possibility of creating a monograph based on the above drafts. In addition, the possibility of producing several related journal articles was discussed. Specific journal article material included (i) a comparison of the probability function versus simulation approaches to power calculations, (ii) a discussion of the use of transformations versus generalized linear model analyses, and (iii) an example of a multi-year, multi-location generalized linear mixed model analysis.

The afternoon session consisted of the following presentations along with group discussion of each.

Kathy Yeater -- Using GLIMMIX to assess multi-year, multi-crop system experiments

David Meek -- A view of model performance assessment procedures

Ted Bailey -- Randomization of factors in a multi-phase experiment

Bruce Craig -- Diffusion test breakpoint determination

George Fernandez -- Issues with some GLIMMIX examples

Business meeting:

The business meeting began at 8:45 am on Friday, July 24, 2009. Ed Gbur presided. Mary Christman and Sara Duke were thanked for organizing a productive and enjoyable meeting. The following items were discussed:

(1) The 2010 meeting will be held in Ames, Iowa and co-hosted by David Meek and Ted Bailey. The date was set for July 8-9. Kathy Yeater will serve as program chair. The USSES group (SCC-13) will be invited to meet jointly next year. Kevin McCarter will serve as the contact person. Bruce Craig volunteered to host the 2011 meeting at Purdue.

(2) The group reviewed and discussed specific goals for the next three years and impacts. The annual report and impact statement are due shortly after the annual meeting. Participants need to send Ed (egbur@uark.edu) accountings of all activities (workshops, papers, presentations, teaching related, etc.) from October 1, 2008 to September 30, 2009 (or since last year's report) that are related to or inspired by their participation in NCCC-170 as soon as possible.

(3) It was decided to proceed with the writing of a monograph as well as some journal articles as discussed during the Thursday morning technical session. Don Bullock and Kathy Yeater will approach the Tri-Societies (Agronomy, Crop Science and Soil Science) to determine if they would be interested in publishing the monograph. If they are not interested, another publisher would be sought.

Ed Gbur agreed to coordinate the writing and to edit the final draft to ensure consistency of style and notation throughout the monograph. The following deadlines were established.

August 15 Revisions of the three drafts presented during the Thursday morning session are due to Ed.

October 1 Final drafts of all additional material are due to Ed.

December 1 Final draft of the entire monograph is ready for submission.

Various individuals agreed to provide additional material on
(1) transformations versus generalized linear mixed models
(2) chi-squared tests
(3) diagnostics for residuals
(4) overdispersion
(5) tests of covariance structures
(6) additional examples
(7) a section on other software, including the analysis of a few of the GLIMMIX examples using the alternative software.

The meeting adjourned at approximately 10:25 a.m.

Accomplishments

Statisticians who consult and do research in an Agricultural Experiment Station environment enable land grant institutions to perform their agricultural research missions more effectively and efficiently than would otherwise be possible. However, most stations have at most one or two professional statisticians who are not, and can not be expected to be, experts in every area of statistics. This multi-state committee brings together statisticians to work cooperatively to determine the best current approaches to common statistical problems and to help guide future directions of sound statistical practice. In addition to group outputs such as workshops, it serves as a resource for its members and a sounding board for new ideas in their applied statistical research. As a result, all members are able to provide more effective assistance to agricultural researchers addressing national research priorities than they would without NCCC-170.<br /> <br /> Outputs:<br /> <br /> Workshops:<br /> <br /> Rob Tempelman, Bruce Craig and Larry Douglass presented a one and a half day mixed model workshop in July, 2009 at the Joint American Dairy Science Association - American Society of Animal Science - Canadian Society of Animal Scienc Meetings in Montreal.

Impact Statements

1. NCCC-170 fosters research to identify and develop statistical methodology applicable to agricultural research and provides a forum for sharing and educating both statisticians and subject-matter scientists in the agricultural, environmental and natural sciences. As a result, all members are able to provide more effective assistance to agricultural researchers addressing national research priorities than they would without NCCC-170.
2. Several members of NCCC-170 have been instrumental in the development of a Section A11 (Biometry) of the American Society of Agronomy. The goal of the section is to provide a forum for members interested in statistics and experimental design from the research and/or teaching points of view. The section serves as a resource and provides training for the larger Tri-Societies&lsquo; membership by sponsoring symposia and workshops at the national and regional meetings. It will also solicit review and methodology manuscripts for the society journals.

Business meeting:

The business meeting began at 9:00 am on Friday, July 9, 2010. Ed Gbur presided. Kathy Yeater, Kevin McCarter (SCC-013 program chair), Ted Bailey and David Meek were thanked for organizing a productive and enjoyable meeting.

The following items were discussed:

(1) The 2011 meeting will be held at Purdue and hosted by Bruce Craig. The date was set for July 7-8. John Stevens will serve as program chair. Rob Tempelman volunteered to host the 2012 meeting at Michigan State.

(2) The group reviewed and discussed specific goals for the next three years and impact statements. The annual report and impact statement are due shortly after the annual meeting. Participants need to send Ed (egbur@uark.edu) accountings of all activities (workshops, papers, presentations, teaching related, etc.) from October 1, 2009 to September 30, 2010 (or since last year's report) that are related to or inspired by their participation in NCCC-170 as soon as possible.

(3) Mary Christman, Kevin McCarter and Walt Stroup will present a workshop on generalized linear mixed models and will participate in a related symposium organized by Kathy Yeater at the ASA-CSSA-SSSA annual meeting in Long Beach in November. Workshops have been offered several times at the Animal and Dairy Science Societies annual meetings. Tentative plans are to do so again. Approaching other professional societies to offer workshops was discussed. The possible use of a webinar format was also mentioned.

(4) Following the discussion at last year's annual meeting, the American Society of Agronomy was contacted and agreed to publish a book on generalized linear mixed models written by project members and participants. The project members involved in the writing are Mary Christman, Susan Durham, Ed Gbur, Matt Kramer, Kevin McCarter, Walt Stroup, Mark West and Linda Young. The manuscript is due to the publishers by October 1, 2010. Ed gave a brief progress report. Six of the seven chapters have been through at least one draft and revision. Outside reviewers have been lined up. George Milliken asked about the possibility of sharing the material with group members. Kathy Yeater volunteered to set up a Sharepoint web site. Ed will check with the Agronomy Society to see if this would be permissible under the contract.

(5) The current project is scheduled to end in September, 2011. The renewal process must be completed this Fall. Projects must make a special request to keep the same number. Otherwise a new number will be assigned. Current members will not automatically be rolled over into the new project. Everyone must submit a new Appendix E form. John Boyer agreed to continue to serve as our Administrative Advisor. Deadlines are as follows.

September 15 -- Initial request due. Includes issues, justification, administrative advisor, and request to retain same project number.

October 15 -- Objectives due.

November 15 -- New Appendix E for everyone (no automatic rollover). Enough forms must be filed to demonstrate sufficient interest.

December 1 -- Complete proposal due.

The current project proposal was reviewed and changes, additions and deletions for the new project were discussed.

The meeting adjourned at approximately 10:35 a.m. A group photograph for the project web site was taken immediately afterward.

Accomplishments

Statisticians who consult and do research in an Agricultural Experiment Station environment enable land grant institutions to perform their agricultural research missions more effectively and efficiently than would otherwise be possible. However, most stations have at most one or two professional statisticians who are not, and can not be expected to be, experts in every area of statistics. This multi-state committee brings together statisticians to work cooperatively to determine the best current approaches to common statistical problems and to help guide future directions of sound statistical practice. In addition to group outputs such as workshops, it serves as a resource for its members and a sounding board for new ideas in their applied statistical research. As a result, all members are able to provide more effective assistance to agricultural researchers addressing national research priorities than they would without NCCC-170.<br /> <br /> Outputs:<br /> <br /> Workshops:<br /> <br /> George Milliken presented a half day work shop entitled "Mixed models analysis using SAS" at the 11th Scientific Conference of Sub-Saharan Africa Network of the International Biometric Society in August, 2009 at Kabarak University, Nakuru, Kenya.<br /> <br /> Larry Madden presented a half-day workshop entitled "Regression Analysis with SAS" at the Annual Meeting of the American Phytopathological Society in Portland OR in August 2009. <br /> <br /> Rob Tempelman presented a half-day workshop entitled "Mixed model analysis of research data" for the Center for Statistical Consulting and Training at Michigan State University (www.cstat.msu.edu) in December, 2009.<br /> <br /> Rob Tempelman presented workshop lectures at the 10th International Microarray Workshop (http://ag.arizona.edu/microarray/workshopJan2010.html) on experimental design, data normalization and statistical inference in January, 2010.<br /> <br /> Linda Young presented workshops entitled "Applied linear and generalized linear mixed models" to the San Diego Chapter of the American Statistical Association and the El Paso Chapter of the American Statistical Association in April, 2010.

Brief Summary of Minutes

Technical program:

The meeting began at 8:30 am on Thursday, July 7, 2011 with opening remarks by Marshall Martin, Associate Director of Agricultural Research Programs, and Bruce Craig.

The technical program consisted of the following presentations.

Nora Bello Hierarchical Bayesian modeling of heterogeneity in the association between milk production and reproduction in dairy cattle

Bryan Pijanowski Studying soundscape dynamics: How 3 TB of acoustic information at a point can be overwhelming to analyze

Linda Young Assessing uncertainty in a spatial setting when both Berkson and classical measurement error are present

Walt Stroup GLMM: Insights & unfinished business - some reflections from the GLIMMIX book experience

Business meeting:

The business meeting began at 9:00 am on Friday, July 8, 2011. Ed Gbur presided. Bruce Craig and John Stevens were thanked for organizing a productive and enjoyable meeting. Minutes from the 2010 meeting were approved.

Ed invited the speakers to send their presentations for posting on the project web site and all participants to send any photographs taken during the meeting.

The following items were discussed:

(1) Julia Sharp presented a proposal from SCC-013 (USSES) to meet jointly with them next year at SAS Institute. Their meeting is tentatively scheduled for June 28-29, 2012. The content of the technical program was discussed. It was decided that if the SAS personnel associated with the development of GLIMMIX and their high performance module would give presentations, then NCCC-170 would be in favor of a joint meeting. Julia will find out if SAS is agreeable to this proposal and report back to the group sometime in August. Rob Tempelman agreed to host the 2013 meeting at Michigan State if we met jointly next year with USSES. If we do not meet jointly, the meeting at Michigan State would be held on July 12-13, 2012. Bruce Craig agreed to serve as program chair.

(2) Ed Gbur reported that the NCCC-170 was renewed for another five years, beginning October 1, 2011. The project number will be retained under the renewal. Current project members were not automatically rolled over into the renewed project. Anyone who has not filled out a new Appendix E to become an official member is encouraged to do so as soon as possible.

(3) The group reviewed and discussed specific goals for the next three years and impact statements. The annual report and impact statement are due shortly after the annual meeting. Participants need to send Ed (egbur@uark.edu) accountings of all activities (workshops, papers, presentations, teaching related items, etc.) from October 1, 2010 to September 30, 2011 (or since last year's report) that are related to or inspired by their participation in NCCC-170 as soon as possible.

(4) Ed Gbur reported that the completed generalized linear mixed model monograph manuscript was sent to the Agronomy Society at the end of June. The title is Analysis of Generalized Linear Mixed Models in the Agricultural and Natural Resources Sciences. Project members involved in the writing are Mary Christman, Susan Durham, Ed Gbur, Matt Kramer, Kevin McCarter, Walt Stroup, Mark West and Linda Young. Publication is scheduled to coincide with the Society's annual meeting in October.

The meeting adjourned at approximately 10:35 a.m. A group photograph for the project web site was taken immediately afterward.

Accomplishments

Accomplishments: Statisticians who consult and do research in an Agricultural Experiment Station environment enable land grant institutions to perform their agricultural research missions more effectively and efficiently than would otherwise be possible. However, most stations have at most one or two professional statisticians who are not, and can not be expected to be, experts in every area of statistics. This multi-state committee brings together statisticians to work cooperatively to determine the best current approaches to common statistical problems and to help guide future directions of sound statistical practice. In addition to producing group outputs such as workshops, the committee serves as a resource for its members and a sounding board for new ideas in their applied statistical research. As a result, all members are able to provide more effective assistance to agricultural researchers addressing national research priorities than they would be without NCCC-170.<br /> <br /> Outputs:<br /> Workshops:<br /> <br /> Nora Bello, Bruce Craig and Rob Tempelman presented a "Mixed Model Workshop" at the Joint Annual Meeting of the American Dairy Science Association and the American Association of Animal Science in New Orleans in July 2011 (day and a half workshop).
