Rmse forecasr
WebA disadvantage of the indicator is its lack of symmetry; for example dt=1 means that the forecast is twice as large as the true value but dt=-0.5 means that the true value is twice as large as the forecast. WebAs expected, the RMSE from the residuals is smaller, as the corresponding “forecasts” are based on a model fitted to the entire data set, rather than being true forecasts. A good way to choose the best forecasting model is to find the model with the smallest RMSE computed using time series cross-validation.
