Variable selection procedure with the adaptive lasso for interval censored and possibly left truncated data
Description
This package provides penalized variable selection tools for the Cox proportional hazards model with interval censored and possibly left truncated data. The main function alacoxIC
performs the variable selection via a penalized nonparametric maximum likelihood estimation (PNPMLE) with an adaptive lasso penalty. The function also finds the optimal thresholding parameter automatically by minimizing the Bayesian information criterion (BIC). The unpenalized nonparametric maximum likelihood estimation for interval censored and possibly left truncated data is also available with the unpencoxIC
function. The asymptotic validity of the methodology is established in Li et al. (2019).
