Case-Cohort Cox Survival Inference


This package uses case-cohort data to estimate log-relative hazard, baseline hazards at each unique event time, cumulative baseline hazard in a given time interval and pure risk on the time interval and for a given covariate profile, under the Cox model. For the corresponding variance estimation, it relies on influence functions and follows the complete variance decomposition, to enable correct analysis of case-cohort data with and without stratification, weight calibration or missing phase-two covariate data.


The package provides functions implementing the methods described in Etievant and Gail (2023). More precisely, it includes
