I am happy to announce our new paper "Univariate-guided sparse regression". It's a new lasso that leverages the signs and magnitude of univariate coefficients . Sparser and more interpretable than the lasso. We're excited! arxiv.org/abs/2501.18360 R: github.com/trevorhastie...

Univariate-Guided Sparse Regression

In this paper, we introduce ``UniLasso'' -- a novel statistical method for sparse regression. This two-stage approach preserves the signs of the univariate coefficients and leverages their magnitude. ...
