Two-Stage Post-Estimation Elastic Net Shrinkage for Gaussian Copula Models: A Variable Selection Framework for Mixed Biomedical Outcomes

This study introduces a pragmatic two-stage post-estimation shrinkage approach that combines Gaussian copula joint modeling with elastic net feature selection for mixed biomedical outcomes. The proposed methodology addresses key challenges in multivariate statistical analysis by first fitting an unpenalized Gaussian co...
