Hi:

I'm interested in using the SAS randomization macros developed by Cassell for a few response that clearly depart from normality. I study plant quantitative genetics and often using linear mixed model analysis of a two factor designs. For example, I'll grow a set of genotypes in each of two environments.

My analyses are usually completed in SAS PROC MIXED. The statements often look like this.

proc mixed covtest data=mydata; class genotypes treatments block; model response=treatments blocks treatment*blocks; random genotypes genotypes*treatments; run;

I've been able to run the randomization macros under in PROC GLM following the examples provided in SUGI paper (251-27), but I can't seem to get things to run in Proc Mixed.

Can anyone suggest code for Proc Mixed models? Thanks Tom
