An Introduction to glmnet - Stanford University
Webthe factor for getting the minimal lambda in lambda sequence, where min (lambda) = lambda.factor * max (lambda). max (lambda) is the smallest value of lambda for which all coefficients are zero. The default depends on the relationship between n (the number of rows in the matrix of predictors) and p (the number of predictors). WebIntroduction. Glmnet is a package that fits generalized linear and similar models via penalized maximum likelihood. The 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. portrait innovations maternity photos
