adaptIVPTis an R package that will help you design and analyze in vitro permeation test (IVPT) data (currently supports parallel replicate design and balanced data).- This package contains 4 functions:
msabefor hypothesis testing (mixed-scaled average bioequivalence)prmsfor calculating passing rates (passing rate mixed scaled)rssfor reestimating sample size (hence adaptive design)PRsurfacefor plotting passing-rate surfaces (passing-rate surface)
