Hi libaiyi,

answering parts (traveling)…

» I have a naive question about the results of sample size based on sampleN.TOST, sampleN.NTIDFDA, sampleN.HVNTID etc.

» For example,
» sampleN.RSABE(CV=0.3)
» …
» n power
» …
» 45 0.80344
»
» I want to know if the target power is 0.8, the sample size is 45 for each group or for whole study.

Type help(sampleN.TOST), etc.
It is always the (total) number of subjects in the study.

» when we apply power.TOST, the sample size we need to fill in should be number in each group or whole study.

As above.
