 When evaluating a probabilistic forecast, the main challenge is that we never observe the true distribution of the underlying process. Over the years, a number of ways have been developed to evaluate probabilistic forecasts. Some methods admit formal statistical tests, while other result in a single number which has a clear interpretation and is easy to compare.

 evaluation of probabilistic forecasts by assigning a numerical score based on the predictive distribution and on the actually
 observed wind power.
