Tracking Signal
A measurement that indicates whether the forecast average is keeping pace with any genuine upward or downward changes in demand. It monitors the forecast to see if it is biased high or low. As used in forecasting, tracking signal is the number of mean absolute deviations that the forecast value is above or below the actual occurrence.
Tracking Signal = (RSFE / count) / MAD
• RSFE = Running Sum of Forecast Errors include all slices, demand and archived forecast
• MAD = Mean Absolute Deviation
• Count = Forecast parameter "# of Slices for Forecast Error Calculation" or Best Fit parameter "Holdout Window".
