RegisterProbability of Success in BE studies [Design Issues]
Recently I was asked to give Probability of success for a proposed BE study, My thinking is Target study power (usually 80%) is POS with additional correction factor due to the variability during study conduct applied to this target power, is my understanding correct?
Challenge is that do you substract or a multiply the variability factor?
e.g. POS = Target Power (90) - 30 (CV)= 60 0r 90X(1-0.30)=63%
