Is my forecast powerful?

The MASE (Mean Absolute Squared Error) is one of the most important indicators for your forecasting model in Tableau.

A value of 1.00 means, that your model is not better than simply taking the last value to forecast (a.k.a. as the naive approach). A value of 0.50 means, that you doubled your prediction accuracy compared to the naive last value approach.
