frailtyROC (version 1.0.0)

Time-Dependent ROC Curve Estimation for Correlated Right-Censored Survival Data

Description

This contains functions that can be used to estimate a smoothed and a non-smoothed (empirical) time-dependent receiver operating characteristic curve and the corresponding area under the receiver operating characteristic curve for correlated right-censored time-to-event data. See Beyene and Chen (2024) .
