%description
The quantile varying coefficient model is robust to data heterogeneity,
outliers and heavy-tailed distributions in the response variable. In
addition, it can flexibly model dynamic patterns of regression
coefficients through nonparametric varying coefficient functions. In this
package, we have implemented the Gibbs samplers of the penalized Bayesian
quantile varying coefficient model with spike-and-slab priors [Zhou et
al.(2023)]<doi:10.1016/j.csda.2023.107808> for efficient Bayesian
shrinkage estimation, variable selection and statistical inference. In
particular, valid Bayesian inferences on sparse quantile varying
coefficient functions can be validated on finite samples. The Markov Chain
Monte Carlo (MCMC) algorithms of the proposed and alternative models can
be efficiently performed by using the package.
