%description
Implements an efficient and powerful Bayesian approach for sparse
high-dimensional linear regression. It uses minimal prior assumptions on
the parameters through plug-in empirical Bayes estimates of
hyperparameters. An efficient Parameter-Expanded
Expectation-Conditional-Maximization (PX-ECM) algorithm estimates maximum
a posteriori (MAP) values of regression parameters and variable selection
probabilities. The PX-ECM results in a robust computationally efficient
coordinate-wise optimization, which adjusts for the impact of other
predictor variables. The E-step is motivated by the popular two-group
approach to multiple testing. The result is a PaRtitiOned empirical Bayes
Ecm (PROBE) algorithm applied to sparse high-dimensional linear
regression, implemented using one-at-a-time or all-at-once type
optimization. More information can be found in McLain, Zgodic, and Bondell
(2022) <arXiv:2209.08139>.
