From: A graphical method of cumulative differences between two subpopulations
Riverside County vs. Butte County; \(n =\) 1478; Kuiper’s statistic is \(0.04624 / \sigma = 1.650\), Kolmogorov’s and Smirnov’s is \(0.04624 / \sigma = 1.650\); resolving both the phenomena corresponding to the fairly flat part and the phenomena corresponding to the very steep part of the cumulative graph (a) for the lowest scores requires at least 100 bins in the reliability diagrams (f and g), but then the rest of the diagrams is very noisy. The statistics of Kuiper and of Kolmogorov and Smirnov do not report much statistically significant deviation between the subpopulations
