WebFeb 23, 2024 · R 2 = 1 − R M S E 2 × ( n − k) ∑ ( y i − y ¯) 2. Now the unit of the RMSE is the unit of the dependent variable, while the R 2 is a proportion. So, numerically you can arbitrarily change RMSE while keeping the R 2 constant by changing the unit of the dependent variable. WebMy understanding is that the test RMSE (or MSE) is the measure of goodness of predicting the validation/test values, while R^2 is a measure of goodness of fit in capturing the variance in the training set. In the real world, what I really care about is generalized prediction accuracy on data I haven't seen.
