The measure for forecasting error among the given options is the Tracking Signal.

Here's how it works:

1. The tracking signal is a measure that indicates whether the forecast average is keeping pace with any genuine upward or downward changes in demand.

2. This is calculated by dividing the cumulative forecast error by the mean absolute deviation.

3. The tracking signal can be used to detect forecast bias. If the tracking signal reaches a predetermined threshold, this may indicate that the forecast is consistently too high or too low.

4. This information can then be used to adjust the forecasting method or parameters to improve future forecasts.

So, the tracking signal is a useful tool for measuring and correcting forecasting error.
