Fit - glmnet x y family cox maxit 1000
WebIntroduction. We will give a short tutorial on using coxnet. Coxnet is a function which fits the Cox Model regularized by an elastic net penalty. It is used for underdetermined (or nearly underdetermined systems) and chooses a small number of covariates to include in the model. Because the Cox Model is rarely used for actual prediction, we will ... WebWhen the family argument is a class "family" object, glmnet fits the model for each value of lambda with a proximal Newton algorithm, also known as iteratively reweighted least …
