R Package: ssanv - Sample size adjustments for nonadherence and variability of input parameters
...ose you want a sample size for a two group difference in normal means but you get your estimate of your variance from a previous study. Then with this package, you can account for the variability of that variance estimate in your sample size calculations. The details are described in:
