Sparse Regression under Correlation and Weak Signals: A Reproducible Benchmark of Classical and Bayesian Methods
Bayesian methods outperform classical ones on prediction error in correlated weak-signal settings, with Horseshoe providing near-nominal coverage and Lasso tying Spike-and-Slab on variable selection F1 score.
