%description
Provides estimation and inference for while-alive regression models
targeting the while-alive loss rate for composite endpoints that include
recurrent events and a terminal event. The implementation supports
flexible time-varying covariate effects through user-selected time bases,
including B-splines, natural splines, M-splines, step functions, truncated
linear bases, interval-local bases, and piecewise polynomials. Inference
can be performed using cluster-robust variance estimators for
cluster-randomized trials, with subject-level (IID) variance as a special
case. The package includes prediction and plotting utilities and K-fold
cross-validation for selecting basis and tuning parameters. Methodology is
based on Fang et al. (2025) <doi:10.1093/biostatistics/kxaf047>.
