WebbTo get the overall error, we add up these errors. we don't take a simple arithmetic mean, but use an RMS of these errors. There are many scientific reasons for this, but my statistical knowledge is far too weak to explain it to you. So basically you calculate the RMS error using the Following Formula: RMS error=Square Root (Σ (e^2)/n) Webb在计算机视觉中，经常会用到重投影误差（Reprojection error）。比如在计算平面单应矩阵和投影矩阵的时候，往往会使用重投影误差来构造代价函数，然后最小化这个代价函 … WebbThe Root Mean Square Error or RMSE is a frequently applied measure of the differences between numbers (population values and samples) which is predicted by an estimator or a mode.

For instance, for each series, you could run a simple benchmark forecast, like the overall mean. This gives you an RMSE benchmark in the holdout sample. Now you run the forecasting method A you are actually interested in, which gives you an RMSE A in the holdout sample.

Any feedback is appreciated. -- WebbThese deviations are called residuals when the calculations are performed over the data sample that was used for estimation and are called errors (or prediction errors) when computed out-of-sample. The RMSD serves to aggregate the magnitudes of the errors in predictions for various data points into a single measure of predictive power.
