Robust Dual-Regularized Variable Selection under Outlier Contamination

arXiv:2609.21342v1 Announce Type: cross Abstract: Real data often contain unusual observations that can exert disproportionate effects on variable selection, especially in complex predictor settings. We propose a two-stage {\it sparse median outer product of gradients (smOPG)} method for variable s…
