%description
Computes regularization paths for L1-penalized support vector machine
(SVM) models, including the standard SVM, receiver operating
characteristic SVM (ROC-SVM), and fraud detection SVM (FD-SVM). The
package implements efficient path algorithms to obtain solutions over a
wide range of regularization parameter values. It also provides
cross-validation for selecting an optimal regularization parameter, along
with functions for prediction, visualization, and summarization of the
fitted models. For more details, see Zhu et al. (2003)
