Dear All,
Potvin et. al. describe the use of GMR = 0.95 in the sample size adaption step of their Methods B/C. If we assume a more extreme null ratio and want to calculate the empirical power at that GMR (via simulation):
Is it reasonable / mandatory to use that GMR in the sample size adaption step?
