Hi everyone, I am having an issue how to account for the extra error term in our mixed statistical model using the SAS mixed procedure. I want to treat it as a split-plot design to come up with an ANOVA table, and one error term should not include the factor L (see equation below). My guess is something like: Proc Mixed data=StrainGauges method=type3; class rep F R C L; model S=F R C FR FC RC FRC L FL RL CL FRL FCL RCL FRCL/ddfm=kr; Random rep(A|B|C) However, I am not sure how to write the random statement (e.g. "Random rep(A*B*C)" or "Random rep(A|B|C)"). Can someone help me to write this code? Thanks in advanced! Josue
