The same sort of process was seen in Minitab and accounts for the multiple tabs under Stat > ANOVA and Stat > Regression, and eventually, Stat > General Linear Model (which … WebbRecently, PROC MIXED was added to the palette of SAS/STAT procedures. One of PROC MIXED strengths is the analysis of statistical models with combined random and fixed effects. Many experimental design situations that had a non-optimal solution in the otherwise powerful GLM procedure have now become much simpler.

WebbModels fit with PROC GLIMMIX can have none, one, or more of each type of random effect. Note that an R-side effect in PROC GLIMMIX is equivalent to a REPEATED effect in the MIXED procedure. The R-side covariance structure in PROC GLIMMIX is the covariance structure that you formulate with the REPEATED statement in the MIXED procedure. mich football game
