RegisterPower Calculation of 2x2 crossover design (SAS) [Software]
Suppose we have 2x2 crossover design with 2 periods, and sample size is given 12 subjects in each seq. (total N=24). How do i calculate power to detect 20% difference between A and B in AUC ?
what std. deviation should i use ? please provide me formula or SAS code! Thanks.
