The Elastic Net penalty encourages a grouping effect, where strongly correlated predictors tend to be in or out of the model together. The computation is done with the function \code{glmpath} from the package of the same name. } \section{Methods}{ \describe{ \item{X = "matrix", y = "numeric", f = "missing"}{signature 1} \item{X = "matrix", y = "factor", f = "missing"}{signature 2} \item{X = "data.frame", y = "missing", f = "formula"}{signature 3} \item{X = "ExpressionSet", y = "character", f = "missing"}{signature 4} } For references, further argument and output information, consult \code{\link{ElasticNetCMA}} } \keyword{multivariate}
