Hi Helmut,

Thanks for your answers (and for the R package ;-)

❝ link=https://cran.r-project.org/package=PowerTOST]PowerTOST[/link] is [image] Open Source (licensed under GPL-3), comes at no cost, was used in numerous publications, textbooks, and even by the [image] … :-D

Could you elaborate on your note of the use of PowerTOST by FDA? It would provide me an additional argument for using PowerTOST for formal sample size estimation in our company.

Thanks,
Willem
