Overall forecasting performance of forecasting models. A Empirical coverage of 50% and 90% prediction intervals for 1-14 days forecast horizon. The dashed line indicates the target coverage level (50% or 90%). B Relative weighted interval score (rWIS) by forecast horizon (7 and 14 days). C Distribution of WIS rankings across all 7701 targets; for each target, rank 1 is assigned to the model with the lowest relative WIS (rWIS) and rank 5 to the model with the highest rWIS
