Stability of a Generalized Debiased Lasso with Applications to Resampling-Based Variable Selection

Jingbo Liu / April 14, 2026

arXiv:2405.03063v2 Announce Type: replace-cross
Abstract: We propose a generalized debiased Lasso estimator based on a stability principle. When a single column of the design matrix is perturbed, the estimator admits a simple update formula that can b…
