Score card provides a quick visual overview over the performance of the CY43r1 scores compared to CY41r2. It is a simplified summary of verify error plots of various domains, scores, parameters etc.
Each error plot is converted into a sequence of symbols (e.g. ) where each symbol indicates for given time step whether or not the CY43r1 is significantly better or worse than the CY41r2.
Symbol legend: for a given forecast step... (d: score difference, s: confidence interval width)
CY43r1 better than CY41r2 statistically highly significant (the confidence bar above zero by more than its height )(d/s>3)
CY43r1 better than CY41r2 statistically significant (d/s≥1)
CY43r1 better than CY41r2, yet not statistically significant (d/s≥0.5)
not really any difference between CY41r2 and CY43r1
CY43r1 worse than CY41r2, yet not statistically significant (d/s≤-0.5)
CY43r1 worse than CY41r2 statistically significant (d/s≤-1)
CY43r1 worse than CY41r2 statistically highly significant (the confidence bar below zero by more than its height) (d/s<-3)
