%description
Builds a LASSO, Ridge, or Elastic Net model with 'glmnet' or 'cv.glmnet'
with bootstrap inference statistics (SE, CI, and p-value) for selected
coefficients with no shrinkage applied for them. Model performance can be
evaluated on test data and an automated alpha selection is implemented for
Elastic Net. Parallelized computation is used to speed up the process. The
methods are described in Friedman et al. (2010)
<doi:10.18637/jss.v033.i01> and Simon et al. (2011)
<doi:10.18637/jss.v039.i05>.
