❝ Not sure whether I understand you correctly. POS is a Bayesian concept, where you need some prior information.


I am sorry I am equally confused in this example where do we find POS? what all I see is Sample size and anticipated power with certain N.

How come we have three different N with same assumptions?

❝ As usual, the T/R-ratio is the killer.


----- :-D:-D Thanks for reiterating my thought all along many of my colleagues are having issue in understanding T/R is main culprit than ISCV in Sample size estimates.

Please edcuate me on how to connect Power with POS?
