Regardless of huge errors, and errors much higher than 100% of the Actuals or Forecast, we interpret accuracy a number between 0% and 100%. Wird verarbeitet... MAD can reveal which high-value forecasts are causing higher error rates.MAD takes the absolute value of forecast errors and averages them over the entirety of the forecast time periods.

As stated previously, percentage errors cannot be calculated when the actual equals zero and can take on extreme values when dealing with low-volume data. It is calculated as the average of the unsigned errors, as shown in the example below: The MAD is a good statistic to use when analyzing the error for a single Wird geladen... However, this interpretation of MAPE is useless from a manufacturing supply chain perspective.

If you are working with a low-volume item then the MAD is a good choice, while the MAPE and other percentage-based statistics should be avoided. The MAPE is scale sensitive and should not be used when working with low-volume data. Sprache: Deutsch Herkunft der Inhalte: Deutschland EingeschrÃ¤nkter Modus: Aus Verlauf Hilfe Wird geladen...
