Overview

About

Maintained by Trevor HastieFirst published 2026-01-261 releasesCRAN page ↗

Fit a univariate-guided sparse regression (lasso), by a two-stage procedure. The first stage fits p separate univariate models to the response. The second stage gives more weight to the more important univariate features, and preserves their signs. Conveniently, it returns an objects that inherits from class 'glmnet', so that all of the methods for 'glmnet' are available. See Chatterjee, Hastie and Tibshirani (2025) doi:10.1162/99608f92.c79ff6db for details.
