Lets now apply elastic net which brings together L1 and L2 regulatization into a single powerful approach. Feb 22 2019 A third commonly used model of regression is the Elastic Net which incorporates penalties from both L1 and L2 regularization. This approach is useful when we decide apriori on what alpha we want to use.

Loading required R packages tidyverse for easy data manipulation and visualization. In this post we will go through an example of the use of elastic net using the VietnamI dataset from the Ecdat package. Glmnet is a package that fits a generalized linear model via penalized maximum likelihood. Elastic Net produces a regression model that is penalized with both the L1-norm and L2-norm.
