The WR package implements various win ratio methodologies for composite endpoints of death and non-fatal events, including the (stratified) proportional win-fractions (PW) regression models (Mao and Wang, 2020 doi:10.1111/biom.13382), (stratified) two-sample tests with possibly recurrent nonfatal event, and sample size calculation for standard win ratio test (Mao et al., 2021 doi:10.1111/biom.13501).
Install WR from CRAN with:
install.packages("WR")
You can install the development version from GitHub with:
# install.packages("devtools")
# devtools::install_github("lmaowisc/WR")
install.packages("WR", repos = c('https://lmaowisc.r-universe.dev', 'https://cloud.r-project.org'))
Here is a basic example.
