%description
Non-proportional hazard (NPH) is commonly observed in immuno-oncology
studies, where the survival curves of the treatment and control groups
show delayed separation. To properly account for NPH, several statistical
methods have been developed. One such method is Max-Combo test, which is a
straightforward and flexible hypothesis testing method that can
simultaneously test for constant, early, middle, and late treatment
effects. However, the majority of the Max-Combo test performed in clinical
studies are unstratified, ignoring the important prognostic stratification
factors. To fill this gap, we have developed an R package for stratified
Max-Combo testing that accounts for stratified baseline factors. Our
package explores various methods for calculating combined test statistics,
estimating joint distributions, and determining the p-values.
