Overview

About

Maintained by Michael KaneFirst published 2017-06-166 releasesCRAN page ↗GitHub ↗

Design and analyze two-stage randomized trials with a continuous outcome measure. The package contains functions to compute the required sample size needed to detect a given preference, treatment, and selection effect; alternatively, the package contains functions that can report the study power given a fixed sample size. Finally, analysis functions are provided to test each effect using either summary data (i.e. means, variances) or raw study data doi:10.18637/jss.v094.c02.
