Understanding the Kolmogorov-Smirnov Test: A Practical Guide with R Examples

The Kolmogorov-Smirnov test (often referenced as the KS test) is recognized as a highly versatile non-parametric statistical tool essential for assessing foundational distributional assumptions in data analysis. Its primary function is twofold: first, to determine if a given sample plausibly originates from a specific theoretical statistical distribution (the one-sample case, or goodness-of-fit), and second, to […]
