%description
Group-Lasso INTERaction-NET. Fits linear pairwise-interaction models that
satisfy strong hierarchy: if an interaction coefficient is estimated to be
nonzero, then its two associated main effects also have nonzero estimated
coefficients. Accommodates categorical variables (factors) with arbitrary
numbers of levels, continuous variables, and combinations thereof.
Implements the machinery described in the paper "Learning interactions via
hierarchical group-lasso regularization" (JCGS 2015, Volume 24, Issue 3).
