Lasso Regression is an extension of linear regression that adds a regularization penalty to the loss function during training. How to evaluate a Lasso Regression model and use a final model to make predictions for new data. How to configure the Lasso Regression model for a new dataset via grid...
Either of the above methods may be used to build the multiple regression model. In fact, both the above methods would work for univariate regression as well – what we did using the regression trendlineearlier. For multiple regression, using the Data Analysis ToolPak gives us a little more he...
