WebLike adjusted R-squared, predicted R-squared can be negative and it is always lower than R-squared. Even if you don’t plan to use the model for predictions, the predicted R-squared still provides crucial information. A key benefit of predicted R-squared is that it can prevent you from overfitting a model.
