In the maximize R model, the first variable selected leads to the highest R2 value when entered initially in the model. As shown in Figure 20, in the case of our model, the first variable entered is Spend_save_quarterly_ratio. The variable is statistically significant. After this, the Clothing_and_shopping variable is entered. At this stage, the R2 value further increases. The model declares that the best two variable combination in the model has been found:

In Figure 5.21, we see the attempt by the model to find the best possible three variable model. The Entertainment variable is entered ...
