Dear ElMaestro

❝ How is the evaluation done? Which model is fitted?

EMA ANOVA:

Sims according to the 'all effects fixed' doctrine as discussed here.
Evaluation of the replicate design with the same ANOVA as for the 2x2x2 crossover. Point estimator and its 90% CI via LSMeans difference.
ABE decision via 90% CI's.

FDA ISC:

Sims with the full mixed model underlying the Proc MIXED code of the FDA. We had it already here in the forum but couln't find at the moment in the meanwhile tons of posts. For a short description see Chow&Liu Chapter 20.5.7.1.. The subject-by-treatment interaction was assumed zero.
Calculate appropriate intra-subject contrast to obtain individual T-R. Analyzed them by an ANOVA with sequence as the solely effect. The intercept of this ANOVA gives the point estimator T-R and its 90% CI.
ABE decision via the 90% CI's.
