Dear all,
Please clarify following Criteria,
We are going to conduct one "Two-Stage" bioequivalence study. In this study initially we had fixed the sample size as maximum of 80 subjects (Both stage1 and stage2).
In stage-1 we include 40 subjects and based on stage1 data we will precede with a maximum sample size of 40 subjects in stage-2 (sample size will be ≤ 40).
Is there any statistical method to decide sample size in stage2?
Regards
Kotu
