WebJun 7, 2024 · – LASSO – Elastic Net • Proc HPreg – High Performance for linear regression with variable selection (lots of options, including LAR, LASSO, adaptive LASSO) – Hybrid versions: Use LAR and LASSO to select the model, but then estimate the regression coefficients by ordinary weighted least squares. (suggested by Efron!) WebJan 1, 2012 · We show that the adaptive lasso enjoys the oracle properties; namely, it performs as well as if the true underlying model were given in advance. Similar to the lasso, the adaptive lasso is shown to be near-minimax optimal. Furthermore, the adaptive lasso can be solved by the same efficient algorithm for solving the lasso.

By allowing a relatively higher penalty for zero coefficients and, lower penalty for nonzero coefficients, the adaptive Lasso hopes to reduce the estima-tion bias and improve variable selection accuracy, compared with the standard Lasso. WebTechnically the Lasso model is optimizing the same objective function as the Elastic Net with l1_ratio=1.0 (no L2 penalty). Read more in the User Guide.
