The goal of SimTOST is to estimate the sample size sample size for a
randomized, three-arm, parallel group phase I trial via simulation.
SimTOST is available on CRAN and can be installed by running the
following code.
install.packages("SimTOST")You can also install the development version of SimTOST from GitHub with:
# install.packages("devtools")
devtools::install_github("smartdata-analysis-and-statistics/SimTOST")The main features of this package is sampleSize function which can be
used to calculate sample size for individual and multiple endpoints.
Various worked examples are available as
vignettes,
with an introduction provided at
Introduction.
