WebFeb 1, 2024 · This article considers simultaneous variable selection and parameter estimation as well as hypothesis testing in censored survival models where a parametric likelihood is not available. For the problem, we utilize certain growing dimensional general estimating equations and propose a penalized generalized empirical likelihood, where … Web(2012) proposed a penalized empirical likelihood (PEL) approach for parameter estima-tion and variable selection with the diverging dimension of covariates (p) and growing dimensional generalized estimating equation. More generally, Tan and Yan (2024) ex-tended the PEL method to generalized linear models and established the oracle property
