The penalty structure can be any combination of an L1 penalty (lasso and fused lasso), an L2 penalty (ridge) and a positivity constraint on the regression coefficients. The supported regression models are linear, logistic and poisson regression and the Cox Proportional Hazards model. Cross-validation routines allow optimization of the tuning parameters. </p></html>Jelle Goeman, Rosa Meijer, Nimisha ChaturvediTue, 06 Nov 2012 00:00:00 -0000
