Equation for rmse
The root-mean-square deviation (RMSD) or root-mean-square error (RMSE) is a frequently used measure of the differences between values (sample or population values) predicted by a model or an estimator and the values observed. The RMSD represents the square root of the second sample moment of the differences between predicted values and observed values or the quadratic mean of these differences. These deviations are called residuals when the calculations are performed ove… WebDescription. E = rmse (F,A) returns the root-mean-square error (RMSE) between the forecast (predicted) array F and the actual (observed) array A. F and A must either be …
