Another Look at Forecast-accuracy Metrics for Intermittent Demand
Preview: Some traditional measurements of forecast accuracy are unsuitable for intermittent-demand data because they can give infinite or undefined values. Rob Hyndman summarizes these forecast accuracy metrics and explains their potential failings. He also introduces a new metric—the mean absolute scaled error (MASE)—which is more appropriate for intermittent-demand data. More generally, he be...
متن کاملCrowdsourced Electricity Demand Forecast
We propose a new approach to forecasting the demand for a commodity in which the commodity supplier asks each consumer to forecast its own demand for the commodity and in return gives a monetary reward that is proportional to the accuracy of the forecast. Such an approach might be applicable when consumer demand for a perishable commodity is uncertain and forecast error leads to waste for produ...
متن کاملTesting Forecast Accuracy
Despite the obvious desirability of formal testing procedures, earlier efforts at assessing the forecast accuracy of an estimated model revolved around the calculation of summary forecast error statistics e.g., see Klein (1991); Clements and Hendry (1993); Wallis (1995); Newbold, Harvey, and Leybourne (1999); and Stock and Watson (1999). Resort to such an informal approach may be ascribed mainl...
متن کاملMeasuring forecast accuracy
It is important to evaluate forecast accuracy using genuine forecasts. That is, it is invalid to look at how well a model fits the historical data; the accuracy of forecasts can only be determined by considering how well a model performs on new data that were not used when estimating the model. When choosing models, it is common to use a portion of the available data for testing, and use the re...
متن کاملAssessing Forecast Accuracy Measures
This paper looks into the issue of evaluating forecast accuracy measures. In the theoretical direction, for comparing two forecasters, only when the errors are stochastically ordered, the ranking of the forecasts is basically independent of the form of the chosen measure. We propose wellmotivated Kullback-Leibler Divergence based accuracy measures. In the empirical direction, we study the perfo...
