Business meeting:
The business meeting began at 9:10 a.m. on Friday, July 18, 2014. Ed Gbur presided. The following items were discussed:
(1) Ed Gbur thanked several people for organizing a productive and enjoyable meeting: Walt Stroup for local arrangements; Bahman Shafii for the technical program; Ellen Paparozzi and Walt Stroup for the cookout/mixer at their home; Stacy Herceg for support and refreshments.
(2) The annual report and impact statement are due shortly after the annual meeting. Participants need to send Ed Gbur (egbur@uark.edu) accountings of all activities (workshops, papers, presentations, grants, teaching related items, etc.) from October 1, 2013 to September 30, 2014 (or since last year’s report) that are related to or inspired by their participation in NCCC-170 as soon as possible.
(3) The 2015 meeting will be held in Mayagüez, Puerto Rico on June 25-26 with Raul Macchiavelli as host. This will be a joint meet with USSES (SCC-013). After some discussion, Mayagüez was chosen as the location over San Juan. Bahman Shafii will serve as program chair. Bahram Momen is the USSES program chair. The 2016 meeting is set for Maryland with Bahram Momen serving as the host. The 2017 meeting is tentatively planned for Arkansas.
(4) Ed Gbur noted that we successfully navigated the mid-term review and that NCCC-170 has been approved to continue through 2016. The notification letter is posted on the project website under this year’s meeting.
(5) The group reviewed progress toward the goals identified at the 2013 meeting. The mixed model workshop materials have been updated and expanded to include generalized linear mixed models and the use of new software. The focus of the genomics workshops has shifted to more current topics and continues to evolve over time. Anyone interested in participating in this endeavor should contact Kathy Yeater. Goals for the next three years were revised based on the discussion.
(6) As part of Kathy Yeater’s project on “Statistics Workshops for Regional Meetings and Web-Based Platforms” that she is facilitating for the American Society of Agronomy, Carla Goad discussed the web based introductory course that Julia Sharp taught and the experimental design/ANOVA course that she taught. Both courses were well received by society members.
As part of the same project, Kathy is looking for volunteers to develop a short course for the Society that introduces the use of statistical analyses in R. Anyone interested should contact Kathy. Carla and Kathy both indicated that there are financial incentives related to this project’s participants.
(7) Nora Bello invited project members to become involved in the mixed model workshops presented at the annual Animal Sciences meetings. Next year’s workshop is July 15-16, 2015 in Orlando. Presenter travel and housing expenses are covered by the Society. The workshops have been well attended with an average of about 80 participants each time it has been presented. Bruce Craig noted that he can make workshop materials available to project participants. The materials can be used with proper acknowledgment of NCCC-170.
(8) The group discussed the issue of remote access participation. Nora Bello volunteered to purchase a good quality microphone and noted that she has access through KSU to Zoom software for facilitating remote participation. Members agreed that there should be a reduced registration fee of $10 for remote participation, with funds being used to reimburse expenses such as the microphone purchase.
(9) Nora Bello solicited suggestions about a topic and speaker for the 2015 Conference on Applied Statistics in Agriculture at Kansas State. She was also interested in input on ways to increase attendance at the conference. Nora encouraged people to send ideas and in particular would welcome statements of support for an alternative date as a way to increase attendance.
The meeting adjourned at approximately 10:55 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 cannot 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 without NCCC-170.

Impacts
- 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 be without NCCC-170.
- Project members provide continuing education for scientists in agriculturally related disciplines in modern statistical analyses of designed experiments in general and specifically in the areas of generalized linear mixed models and statistical techniques in genomics applications. Examples of such activities and their immediate impacts for the current reporting period are listed in the Accomplishments section of this report.
- Project members collaborate in research projects with scientists in agricultural related disciplines to develop and use proper statistical design and analysis methodology well beyond standard textbook applications. These efforts often result in competitive grant participation and refereed publications. Each of these impacts is listed in the Accomplishments and Publications sections of this report.
