[TatianaButenko]

Пожалуйста, помогите перевести.mean absolute scaled error Выражение встречается в следующем контексте:
The Box-Jenkins procedure (after the major contribution of Box and Jenkins (Box et al. (2008)) to providing a general strategy for time series forecasting) is summarized in sec. 2.1.4. It includes model identification, model estimation and finally model checking. A possible model having been identified and the parameters estimated, a method to forecast the future values of the considered stochastic process is provided in sec. 2.1.5 along with some measures of forecasting accuracy, namely the mean absolute error (MAE), the root mean square error (RMSE), the mean absolute percentage error (MAPE) and the mean absolute scaled error (MASE).
Заранее спасибо
