Interval-Censored Survival Analysis: A Comparative Monte Carlo Study of Weibull AFT and Cox Proportional Hazards Models

Abstract

This study investigates the comparative performance of the Weibull accelerated failure time (AFT) model and the Cox proportional hazards (PH) model for interval-censored Weibull data. The study emphasizes baseline survival function precision and confidence interval coverage at key quantile-based time points across the survival curve.
