Mean absolute percentage error and bias in economic forecasting. (English) Zbl 1239.91124
Summary: This article develops a simple theoretical framework to show how forecasters may bias downward point predictions under the assumption that the asymmetric loss function is directly related to the (Mean) Absolute Percentage Error \((M)APE\).
