I create the Elastic Net model using the scaled data. I will use different values of alpha to find the best model with the least error. Using alpha = 0. The error is 42.1% I notice that this model includes the So, Pop, NW, and Wealth factors that the stepwise regression model didn’t. The mean cross validated error of this model is 42.1% [Show More]
