Variable Selection with Broken Adaptive Ridge Regression for Interval-Censored Competing Risks Data
Fatemeh Mahmoudi, Chenxi Li, Kaida Cai +1
Competing risks data refer to situations where the occurrence of one event pre- cludes the possibility of other events happening, resulting in multiple mutually exclusive events. T…

Variable selection in the joint frailty model of recurrent and terminal events using Broken Adaptive Ridge regression
Christian Chan, Fatemeh Mahmoudi, Chel Hee Lee +2
We introduce a novel method to simultaneously perform variable selection and estimation in the joint frailty model of recurrent and terminal events using the Broken Adaptive Ridge…

Penalized Variable Selection with Broken Adaptive Ridge Regression for Semi-competing Risks Data
Fatemeh Mahmoudi, Xuewen Lu
Semi-competing risks data arise when both non-terminal and terminal events are considered in a model. Such data with multiple events of interest are frequently encountered in medic…
