What is a good forecast bias?

A forecast bias occurs when there are consistent differences between actual outcomes and previously generated forecasts of those quantities; that is: forecasts may have a general tendency to be too high or too low. A normal property of a good forecast is that it is not biased.

What is tracking signal in forecasting?

Tracking Signal is used to determine the larger deviation (in both plus and minus) of Error in Forecast, and is calculated by the following formula: Tracking Signal = Accumulated Forecast Errors / Mean Absolute Deviation. For example, when Errors (F1 and F2) in Forecast occur, each Mean Absolute Deviation (MAD) is 45.

What makes a good forecasting?

A good forecast is “unbiased.” It correctly captures predictable structure in the demand history, including: trend (a regular increase or decrease in demand); seasonality (cyclical variation); special events (e.g. sales promotions) that could impact demand or have a cannibalization effect on other items; and other, …

What is the difference between forecast accuracy and bias?

Forecast error is a measure forecast accuracy. Bias, mean absolute deviation (MAD), and tracking signal are tools to measure and monitor forecast errors. BIAS = Historical Forecast Units (Two-months frozen) minus Actual Demand Units.

How do you evaluate prediction accuracy?

When measuring the accuracy of a prediction the magnitude of relative error (MRE) is often used, it is defined as the absolute value of the ratio of the error to the actual observed value:│(actual−predicted)/actual│or │(y−ŷ)/y│. When multiplied by 100% this gives the absolute percentage error (APE).
