How to calculate tracking signal in R?
Tracking signal is computed as the running sum of forecast error (RSFE) divided by MAD. We compute RSFE by summing up the forecast errors over time. Forecast errors for January is the difference between its actual and forecast sales. RSFE for January is equal to the cumulative forecast errors.
