STATISTICAL MEASURE
Root Mean Squared Error; RMSE; RMSD; Root-mean-square error; Normalized root mean squared deviation; NRMSD; Root mean squared error; RMS error; Root mean square deviation; Root mean square error
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.
