A unified approach to variable selection for Cox’s proportional hazards model with interval-censored failure time data

Statistical Methods in Medical Research, 2021
Cox’s proportional hazards model is the most commonly used model for regression analysis of failure time data and some methods have been developed for its variable selection under different situations. In this paper, we consider a general type of failure
