Figure 6

Illustrating the Kolmogorov–Smirnov test statistic (KS). Simulations with synthetic data generated according to Gaussian (a,b) and exponential (c) probability distributions. The results are present in a similar manner as Fig. 5. Each panel shows a reference case (R), and two additional cases with a large (L) and small (S) change in mean \(\mu\) (a,c) and standard deviation \(\sigma\) (b). The resulting KS values are shown in the figure legend. In all panels, the R population has a size of 60,000, while the S and L populations have a smaller population size of 6,000. This is done to roughly match the difference in population sizes in Fig. 5.
