%description
Provides tools for sparse regression modelling with grouped predictors
using the group subset selection penalty. Uses coordinate descent and
local search algorithms to rapidly deliver near optimal estimates. The
group subset penalty can be combined with a group lasso or ridge penalty
for added shrinkage. Linear and logistic regression are supported, as are
overlapping groups.
