Bayesian methods outperform classical sparse regression in prediction and uncertainty

By PulseAugur Editorial · [1 sources] ·

A new benchmark study evaluated six sparse regression methods, comparing classical approaches like Lasso with Bayesian techniques such as Horseshoe and Spike-and-Slab. The research found that Bayesian methods generally offered superior prediction error and more accurate uncertainty estimates, with the Horseshoe prior achieving near-nominal coverage. However, for variable selection, Lasso and Spike-and-Slab performed comparably, suggesting Lasso remains a practical choice when full posterior estimates are not required. AI

IMPACT Provides a comparative analysis of regression techniques, informing practitioners on method selection for prediction and variable selection under challenging data conditions.

    Sparse Regression under Correlation and Weak Signals: A Reproducible Benchmark of Classical and Bayesian Methods

    arXiv:2605.00835v1 Announce Type: new Abstract: Choosing between classical and Bayesian sparse regression methods involves a real trade-off: penalized estimators like Lasso run in milliseconds but give no uncertainty estimates,while Horseshoe and Spike-and-Slab priors produce ful…
