ZTRecur: Analysis for Zero-Truncated Recurrent Event Data

Provides nonparametric and Cox-type regression methods for analyzing zero-truncated recurrent event data with supplementary information. Key features include estimating rate and mean functions under nonparametric marginal models; estimating time-constant regression coefficients under standard and stratified Andersen-Gill (AG) models; and estimating time-varying covariate effects under stratified and nonstratified Cox-type models. Standard errors (SEs) are estimated using sandwich-based variance estimators for nonstratified models and resampling-based procedures for stratified models.
