Dear Detlew & Helmut,

Sorry to cut in. Thank you both for the great summary of the two-stage approach. It sounds like that it is possible to implement all these using R or into bear together with PowerTOST.

❝ [...]

❝ CVintra: 0.1821 (=18.21%)

OK, the example is from WLN. CV_intra = 18.21% (for C_max?) with 12 subjects. So it is not a HVD, is it? Does EMA or FDA accept the two-stage BE if it is the case?

❝ [...]

❝ sampleN.TOST(alpha=0.0294, targetpower=0.80, theta0=0.95, CV=0.1821, design='2x2')

Nice explanations and thank you both again.
