%description
A program that conducts group variable selection for quantile and robust
mean regression (Sherwood and Li, 2022). The group lasso penalty (Yuan and
Lin, 2006) is used for group-wise variable selection. Both of the quantile
and mean regression models are based on the Huber loss. Specifically, with
the tuning parameter in the Huber loss approaching to 0, the quantile
check function can be approximated by the Huber loss for the median and
the tilted version of Huber loss at other quantiles. Such approximation
provides computational efficiency and stability, and has also been shown
to be statistical consistent.
