%description
Implements variational Bayesian algorithms to perform scalable variable
selection for sparse, high-dimensional linear and logistic regression
models. Features include a novel prioritized updating scheme, which uses a
preliminary estimator of the variational means during initialization to
generate an updating order prioritizing large, more relevant,
coefficients. Sparsity is induced via spike-and-slab priors with either
Laplace or Gaussian slabs. By default, the heavier-tailed Laplace density
is used. Formal derivations of the algorithms and asymptotic consistency
results may be found in Kolyan Ray and Botond Szabo (2020)
<doi:10.1080/01621459.2020.1847121> and Kolyan Ray, Botond Szabo, and
Gabriel Clara (2020) <arXiv:2010.11665>.
