Dear all

Dr Anders Fuglsang discussed in his paper

Mitigation of the convergence issues associated with semi-replicated bioequivalence data. Pharmaceutical Statistics. 2021;1–3
used the proc mixed in RTR/TRR/RRT design in ABE

I think that using proc mixed to fit RTR/TRR/RRT design is not suitable, because in most cases proc mixed produced Estimated G matrix is not positive definite.

So proc GLM recommended by FDA and Emea is more appropriate in the Semi-replicated designs
