Webb25 nov. 2024 · The idea behind the KS test is simple: if two samples belong to each other, their empirical cumulative distribution functions (ECDFs) must be quite similar. This suggests that we can evaluate their similarity by measuring the differences between the ECDFs. To achieve this, the KS test finds the maximum distance between the ECDFs. china screen filter cylinderWebb24 mars 2024 · Uniform Distribution.
