WebbIn this case, it is required to supply the original data x= and y= as additional named arguments to predict () or coef (). The workhorse predict.glmnet () needs to update the model, and so needs the data used to create it. The same is true of weights, offset, penalty.factor, lower.limits , upper.limits if these were used in the original call. Webbtidymodels – Extract model coefficients for all cross validated folds As I’ve discussed previously, we sometimes don’t have enough data where doing a train/test split makes sense. As such, we are better off building our model using cross-validation.
