» Hi Libaiyi,
» » I am confused about the relationship between power and period. Are the power calculation method applied in 2*2, 3*3 and 2*4 designs the same?:-D For example, if I have the result like this of the study design as T-S-R, could I use the same method to calculate power separately for T-R and S-R? Should I get two power as the result? And, what about parallel design?

That table looks strange. You seem to have a pair for which the CI is not estimable?? And what about alpha 0.1? Would you be after a two-sided CI with 80% coverage (yes I am aware of the ridiculous alpha in the usual SAS code for BE, but is this table derived from one such)?

I have no idea what the intention is, it just looks strange to me, and I am sure that if I got such a table in one of my studies then I would not be answering the question I was really asking.

Edit: screwed up post deleted ;-) [Ohlbe]

I could be wrong, but...

Best regards,

No, of course you do not need to audit your CRO if it was inspected in 1968 by the agency of Crabongostan.
