Root relative squared error 中文
Web3 Jan 2024 · The Relative Squared Error (RSE) is a relative metric that divides the squared error of a predictive model by the squared error of a simple model. In general, one uses the average of the realized values as a simple model. The image below shows the mathematical formula of the RSE. , where: n: represents the number of observations WebCalculation of the relative root mean square (RRMS) error in JSim: RRMS error = RMS error / σw. - Where RMS error is the root mean square error of the model fit to data (See …
