February 28, 2012 8 am – 5 pm Instructor: Dr. Walter Stroup, Department of Statistics, University of Nebraska, Lincoln, NE. Workshop Description The statistical tools available in the agricultural and natural resource sciences have progressed from basic t-tests to ANOVA to Mixed Models and now Generalized Linear Mixed Models. Generalized and Mixed Model applications are now available in a myriad of statistical software packages, SAS Proc GLIMMIX being the most flexible and widely applicable. This workshop will serve as an introduction to mixed models, focusing on their application in aquaculture. Topics for discussion in the workshop will be: Review and definition of fixed, random, and mixed models; how mixed model analysis builds upon and how it differs from previous generations of statistical analysis (why do mixed models matter?); statistical models for common applications including split-plot experiments and designs with repeated measures; how statistical analysis differs for normal and non- normal distribution of responses; and mixed model concepts of power, precision, and sample size essential for planning experiments. All topics will be discussed using real data examples from aquaculture and related disciplines. While mixed models may be implemented with numerous software packages, this workshop will focus on the GLIMMIX procedure in the SAS software suite. The workshop is lecture-based so laptop computers are not necessary for attendance. Prior to the workshop, participants will be provided a packet of workshop materials used during the course that will include lecture materials and applicable data and code.
