MSE vs. RMSE: Which Metric Should You Use? - Statology

WebR-squared measures how much prediction error we eliminated Without using regression, our model had an overall sum of squares of 41.1879 41.1879. Using least-squares regression reduced that down to 13.7627 13.7627. So the total reduction there is 41.1879-13.7627=27.4252 41.1879−13.7627 = 27.4252.
