# RMSTpowerBoost

`RMSTpowerBoost` provides power and sample size tools for study designs that
use restricted mean survival time (RMST). The package supports direct RMST
modeling with analytical and bootstrap-based procedures for settings that
include linear covariate adjustment, stratification, semiparametric additive
effects, and covariate-dependent censoring.

The package includes both an R interface and a Shiny application.

## Guides

- [Main package guide](https://uthsc-zhang.github.io/RMSTpowerBoost-Package/articles/RMSTpowerBoost-Main.html)
- [Data generation guide](https://uthsc-zhang.github.io/RMSTpowerBoost-Package/articles/RMSTpowerBoost-DataGen.html)
- [Shiny application guide](https://uthsc-zhang.github.io/RMSTpowerBoost-Package/articles/RMSTpowerBoost-App.html)

## Key Features

- Linear IPCW-based RMST power and sample size calculations.
- Additive and multiplicative stratified models for multi-center or highly
  stratified studies.
- Bootstrap-based semiparametric GAM procedures for nonlinear covariate
  effects.
- Analytical and simulation-based methods for covariate-dependent censoring
  under a single censoring mechanism.

## Installation
