Dear Mittyri and all,

❝ Are you working with Replicate study? The things are different there


Its a 2x2 crossover study.

❝ I think you can provide the SAS code above, so all experts will understand that all effects are still fixed, and the reason of random part there is just an F test.


proc glm data=replicate;
class formulation subject period sequence;
model logDATA= sequence subject (sequence) period formulation;
estimate "test-ref" formulation -1+1;
test h=sequence e=subject(sequence);
lsmeans formulation / adjust=t pdiff=control("R") CL alpha=0.10;
run;

This is Method A from EMA Q&A guidance. Ideally in GLM all effects are fixed.
Can we call here sub(seq) as a fixed effect?
