Jul 1, 2014. Whether the forecast or the actual is used as the denominator in the equation, MAPE suffers because it is bounded on the lower end – you cannot go lower than zero percent – but is unbounded on the upper end – the percentage error can be infinite. This is a particular problem if the denominator is small or.

This paper presents a forecasting method to reduce estimation bias using recalled data. This is because a large error in recall increasingly biases forecast values positively as the recalled quantity increases. The essence of this is.
