%description
Fits group-regularized generalized linear models (GLMs) using the
spike-and-slab group lasso (SSGL) prior introduced by Bai et al. (2022)
<doi:10.1080/01621459.2020.1765784> and extended to GLMs by Bai (2023)
<arXiv:2007.07021>. This package supports fitting the SSGL model for the
following GLMs with group sparsity: Gaussian linear regression, binary
logistic regression, Poisson regression, negative binomial regression, and
gamma regression. Stand-alone functions for group-regularized negative
binomial regression and group-regularized gamma regression are also
available, with the option of employing the group lasso penalty of Yuan
and Lin (2006) <doi:10.1111/j.1467-9868.2005.00532.x>, the group minimax
concave penalty (MCP) of Breheny and Huang
<doi:10.1007/s11222-013-9424-2>, or the group smoothly clipped absolute
deviation (SCAD) penalty of Breheny and Huang (2015)
<doi:10.1007/s11222-013-9424-2>.
