WebHow can I interpret RMSE? RMSE is exactly what's defined. $24.5 is the square root of the average of squared differences between your prediction and your actual observation. Taking squared differences is more common than absolute difference in statistics, as you might have learnt from the classical linear regression. It confuses me a little. WebR 2 represents the proportion of total variability of the y -value that is accounted for by the independent variable x. For the specific case when there is only one independent variable X (i.e., simple linear regression), one can show that R 2 = r 2, where r is correlation coefficient between X and Y.
