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.

seq1 seq2 period1(AUC) period2(AUC)
AB    BA     ...          ...

The difference between a surrogate and a true endpoint
is like the difference between a cheque and cash.
You can get the cheque earlier but then,
of course, it might bounce.    Stephen Senn
