%description
Fits sparse frequentist GAMs (SF-GAM) for continuous and discrete
responses in the exponential dispersion family with the group lasso, group
smoothly clipped absolute deviation (SCAD), and group minimax concave
(MCP) penalties <doi:10.1007/s11222-013-9424-2>. Also fits sparse Bayesian
generalized additive models (SB-GAM) with the spike-and-slab group lasso
(SSGL) penalty of Bai et al. (2021) <doi:10.1080/01621459.2020.1765784>.
B-spline basis functions are used to model the sparse additive functions.
Stand-alone functions for group-regularized negative binomial regression,
group-regularized gamma regression, and group-regularized regression in
the exponential dispersion family with the SSGL penalty are also provided.
