mean absolute error (MAE) are regularly employed in model evaluation studies. Willmott and Matsuura (2005) have sug- gested that the RMSE is not a good indicator of average model performance and might be a misleading indicator of average error, and thus the MAE would be a better metric for...
Case study in evaluating time series prediction models using the relative mean absolute error. The American Statistician, 70(3):285-292.Reich, N.G.; Lessler, J.; Sakrejda, K.; Lauer, S.A.; Iamsirithaworn, S.; Cummings, D.A. Case study in evaluating time series prediction models ...
We study in this paper the consequences of using the Mean Absolute Percentage Error (MAPE) as a measure of quality for regression models. We prove the existence of an optimal MAPE model and we show the universal consistency of Empirical Risk Minimization based on the MAPE. We also show that...

Table 6. Error independence test results for each ARMA-GJR-GARCH model. Next, the checking of the accuracy of the ARMA-GJR-GARCH model for each stock needs to be carried out. This examination used the mean absolute error (MAE) and root-mean-squared error (RMSE) measures. The MAE and...
Intuitive Interpretation The root mean square error is a simple metric that provides a straightforward interpretation of the model’s overall error, making it accessible to people without a solid statistical background. It is an absolute measure of the average distance that the data points fall from...
The HDI based on the geometric mean of the component indicators is extremely sensitive to the lower bound—when the value of an indicator approaches its lower bound, the HDI approaches zero and all corresponding marginal rates of substitutions degenerate beyond a reasonable interpretation. In the ...

To provide an intuitive estimate of shoreline mapping accuracy that did not overly penalise these validation method errors, we used Mean Absolute Error (MAE; the arithmetic average of absolute errors) as our primary accuracy assessment metric, but also include RMSE in tabled results (Willmott and ...
