Symbol legend: for a given forecast step... (d: score difference, s: confidence interval width)
Cy38r1 far better than Cy37r3 statistically significant (the confidence bar above zero by more than its height )(d/s>3)
Cy38r1 better than Cy37r3 statistically significant (d/s≥1)
Cy38r1 better than Cy37r3, yet not statistically significant (d/s≥0.5)
not really any difference between Cy37r3 and Cy38r1
Cy38r1 worse than Cy37r3, yet not statistically significant (d/s≤-0.5)
Cy38r1 worse than Cy37r3 statistically significant (d/s≤-1)
Cy38r1 far worse than Cy37r3 statistically significant (the confidence bar below zero by more than its height) (d/s<-3)
Statistical significance evaluated by paired t-test for 95% significance level.
