Time-Varying Restricted Mean Survival Time from Survival Matrices R package tvrmst version 0.0.6 Utilities for restricted mean survival time (RMST) and time-varying restricted mean survival time quantities computed from survival curves provided on a time grid. The package is model-agnostic and accepts only a time vector and survival matrices, returning RMST-based quantities and bootstrap summaries. For restricted mean survival time methodology, see Royston and Parmar (2013) <doi:10.1186/1471-2288-13-152>.
