For example, when measuring the average difference between two time series x 1 , t {\displaystyle x_{1,t}} and x 2 , t {\displaystyle x_{2,t}} , the formula becomes RMSD = ∑ If your RMSE drops considerably and tests well out of sample, then the old model was worse than the new one. http://compaland.com/mean-square/what-is-root-square-mean-error.html

However, although the smaller the RMSE, the better, you can make theoretical claims on levels of the RMSE by knowing what is expected from your DV in your field of research. I see your point about DV range and RMSE. By using this site, you agree to the Terms of Use and Privacy Policy. https://en.wikipedia.org/wiki/Root-mean-square_deviation

RMSD is a good measure of accuracy, but only to compare forecasting errors of different models for a particular variable and not between variables, as it is scale-dependent.[1] Contents 1 Formula Root Mean Square Error Excel It means that there is no absolute good or bad threshold, however you can define it based on your DV. error will be 0.

In hydrogeology, RMSD and NRMSD are used to evaluate the calibration of a groundwater model.[5] In imaging science, the RMSD is part of the peak signal-to-noise ratio, a measure used to Need more assistance?Fill out our online support form or call us toll-free at 1-888-837-6437. For example, if all the points lie exactly on a line with positive slope, then r will be 1, and the r.m.s. Mean Square Error Formula For the second question, i.e., about comparing two models with different datasets by using RMSE, you may do that provided that the DV is the same in both models.
