%description
Approximate Bayesian regularization using Gaussian approximations. The
input is a vector of estimates and a Gaussian error covariance matrix of
the key parameters. Bayesian shrinkage is then applied to obtain
parsimonious solutions. The method is described on Karimova, van Erp,
Leenders, and Mulder (2024) <DOI:10.31234/osf.io/2g8qm>. Gibbs samplers
are used for model fitting. The shrinkage priors that are supported are
Gaussian (ridge) priors, Laplace (lasso) priors (Park and Casella, 2008
<DOI:10.1198/016214508000000337>), and horseshoe priors (Carvalho, et al.,
2010; <DOI:10.1093/biomet/asq017>). These priors include an option for
grouped regularization of different subsets of parameters (Meier et al.,
2008; <DOI:10.1111/j.1467-9868.2007.00627.x>). F priors are used for the
penalty parameters lambda^2 (Mulder and Pericchi, 2018
<DOI:10.1214/17-BA1092>). This correspond to half-Cauchy priors on lambda
(Carvalho, Polson, Scott, 2010 <DOI:10.1093/biomet/asq017>).
