Sample size procedure
to calculate the size of a sample necessary
to compare two independent samples,
one sample against a fixed value or
parameter and sample size calculation for
correlated or paired samples. It is also
possible to calculate the sample size for
an equality analysis. The user can specify
any power (error 2) or alpha (error 1) value.
Useful for the analysis of randomized controlled trials (RCT).
