Description Note Author(s) References See Also
Extends the glmnet package with "relaxation", done by running glmnet once on the entire predictor matrix, then again on each different subset of variables from along the regularization path. Penalty may be lasso (alpha = 1) or elastic net (0 < alpha < 1). For this version, family may be "gaussian" or "binomial" only. Takes advantage of fast fortran code from the glmnet package.
This is a preliminary release and several additional features are planned for later versions.
Stephan Ritter, with design contributions from Alan Hubbard.
Much of the code (and some help file content) is adapted from the glmnet package, whose authors are Jerome Friedman, Trevor Hastie and Rob Tibshirani.
