The score card provides a quick visual overview over the performance of the cycle 43r3 scores compared to cycle 43r1. It is a simplified summary of verify error plots for various domains, scores, parameters etc.
Each error plot is converted into a sequence of symbols (e.g. ) where each symbol indicates for a given time step whether or not the cycle 43r3 is significantly better or worse than the cycle 43r1.
Symbol legend: for a given forecast step... (d: score difference, s: confidence interval width)
cycle 43r3 better than cycle 43r1 statistically highly significant (with 99.7% confidence)
cycle 43r3 better than cycle 43r1 statistically significant (with 95% confidence)
cycle 43r3 better than cycle 43r1, yet not statistically significant (with 68% confidence)
not really any difference between cycle 43r1 and cycle 43r3
cycle 43r3 worse than cycle 43r1, yet not statistically significant (with 68% confidence)
