Bayesian Model Averaging under Predictor Redundancy via Density-Ratio Posterior Compression
Hanqing Li, Xuewen Lu, Yuting Chen
Bayesian model averaging in support-indexed regression induces a posterior distribution over active predictor supports. Under predictor redundancy, posterior mass can spread across…

Bernstein-von Mises Theorem for Sparse Generalized Linear Model
Hanqing Li, Xuewen Lu
We study spike-and-slab priors for generalized linear models with possible grouped sparsity. The main result is an oracle Bernstein--von Mises theorem for the fractional posterior…
