Parameter Description: Standard Deviation

Arguments

stDev

The standard deviation under which the sample size or power calculation is performed, default is 1. For two-armed trials, it is allowed to specify the standard deviations separately, i.e., as vector with two elements. If meanRatio = TRUE is specified, stDev defines the coefficient of variation sigma / mu2.
