WitrynaThe regularization path is computed for the lasso or elastic net penalty at a grid of values (on the log scale) for the regularization parameter lambda. The algorithm is extremely fast, and can exploit sparsity in the input matrix x. It fits linear, logistic and multinomial, poisson, and Cox regression models. WitrynaLike ridge and lasso regression, a regularization penalty on the model coefficients can also be applied with logistic regression, and is controlled with the parameter C. In fact, the same L2 regularization penalty used for ridge regression is turned on by default for logistic regression with a default value C = 1. Note that for both Support ...
