Overview

About

Maintained by Isaac RayFirst published 2010-12-136 releasesCRAN page ↗

The COSSO regularization method automatically estimates and selects important function components by a soft-thresholding penalty in the context of smoothing spline ANOVA models. Implemented models include mean regression, quantile regression, logistic regression and the Cox regression models.
