Power TOST question [Power / Sample Size]
Dear Achievwin,
Call the man page of the function
That is valid for all the other sample size estimating functions.
The power calculating functions accept a single number as sample size, here also the total.
Also accepted a vector of sample sizes, here meaning the sample sizes of groups.
❝ When we use pa.ABE for parallel study N determination output gives N for certain power (e.g. if N=424 for 85% power) is this N is for total (N=424) or per arm (212+212)?
Call the man page of the function
sampleN.TOST()
and read under DetailsThe estimated sample size gives always the total number of subjects (not subject/sequence in crossovers or subjects/group in parallel designs – like in some other software packages)."
