%description
Bayesian regularized quantile regression utilizing sparse priors to impose
exact sparsity leads to efficient Bayesian shrinkage estimation, variable
selection and statistical inference. In this package, we have implemented
robust Bayesian variable selection with spike-and-slab priors under
high-dimensional linear regression models (Fan et al. (2024)
<doi:10.3390/e26090794> and Ren et al. (2023) <doi:10.1111/biom.13670>),
and regularized quantile varying coefficient models (Zhou et al.(2023)
<doi:10.1016/j.csda.2023.107808>). In particular, valid robust Bayesian
inferences under both models in the presence of heavy-tailed errors can be
validated on finite samples. Additional models including robust Bayesian
group LASSO and robust Bayesian binary LASSO are also included. The Markov
Chain Monte Carlo (MCMC) algorithms of the proposed and alternative models
are implemented in C++.
