\(n =\) 6637; Kuiper’s statistic is \(0.2730 / \sigma = 22.24\), Kolmogorov’s and Smirnov’s is \(0.2730 / \sigma = 22.24\); the reliability diagrams with 10 bins each (c and d) smooth the black curve too much, while the reliability diagrams with 50 bins each (e and f) display overly noisy variations in the gray curve. The empirical cumulative graph (a) matches its ground-truth expectations (b) well, though the oscillations at low scores are a bit hard to discern in the cumulative graphs. The metrics of Kuiper and of Kolmogorov and Smirnov report profoundly statistically significant deviation, taking values many times larger than \(\sigma\)
