%description
Generalized additive model selection via approximate Bayesian inference is
provided. Bayesian mixed model-based penalized splines with
spike-and-slab-type coefficient prior distributions are used to facilitate
fitting and selection. The approximate Bayesian inference engine options
are: (1) Markov chain Monte Carlo and (2) mean field variational Bayes.
Markov chain Monte Carlo has better Bayesian inferential accuracy, but
requires a longer run-time. Mean field variational Bayes is faster, but
less accurate. The methodology is described in He and Wand (2023)
<arXiv:2201.00412>.
