%description
A Low Rank Correction Variational Bayesian algorithm for high-dimensional
multi-source heterogeneous quantile linear models. More details have been
written up in a paper submitted to the journal Statistics in Medicine, and
the details of variational Bayesian methods can be found in Ray and Szabo
(2021) <doi:10.1080/01621459.2020.1847121>. It simultaneously performs
parameter estimation and variable selection. The algorithm supports two
model settings: (1) local models, where variable selection is only applied
to homogeneous coefficients, and (2) global models, where variable
selection is also performed on heterogeneous coefficients. Two forms of
parameter estimation are output: one is the standard variational Bayesian
estimation, and the other is the variational Bayesian estimation corrected
with low-rank adjustment.
