Predicted Rsquare
I wanted to use predicted Rsquare to test if my model is overfitting or not. I am not really familiar with this, so I have a few questions regarding predicted Rsquare. 1. How much smaller for the predicted Rsquare is a sign of overfitting? If the Adjusted R-square is 0.94, and the predicted R-square is 0.84, is it okay? 2. I don't fully understand how the predicted Rsquare was calcuated. I kn...
