Webfamily should be "gaussian" for continuous Y, "binomial" for binary Y, "cox" for Y of type Surv standardize whether the predictors should be standardized or not. Default is TRUE. alpha the elastic net mixing parameter: alpha=1 yields the L1 penalty (lasso), alpha=0 yields the L2 penalty. Default is alpha=1 (lasso). Web• model.cv.glmnet <- cv.glmnet(y=y, x=X, offset="model.gam fitted values") • model.gam <- gam(y ~ s(z) + ..., offset="model.cv.glmnet fitted values") ... If family="cox" then the weights argument must be provided and should correspond to a status variable (1-censor). For other models it should correspond to a custom weights variables to be used

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 ... WebFit a generalized linear model via penalized maximum likelihood.
