%description
Filter, wrapper, and embedded feature-selection methods behind a
consistent set of functions that share one calling convention and one
return type: correlation and chi-squared filters, information gain, LASSO
and elastic net, Bayesian model comparison, Boruta, recursive feature
elimination, random forest importance, multivariate adaptive regression
splines, support vector machine recursive feature elimination, stepwise
selection, and principal component / singular value decomposition helpers.
The implemented methods follow Tibshirani (1996)

only required by the functions that use them.
