For example, you can change the significance level or conduct a one-sided test. Kolmogorov–Smirnov test - Wikipedia In statistics, the Kolmogorov–Smirnov test (K–S test or KS test) is a nonparametric test of the equality of continuous (or discontinuous, see Section 2.2), one-dimensional probability distributions that can be used to compare a sample with a reference probability distribution (one-sample K–S test), or to compare two samples (two-sample K–S test).

The Kolmogorov-Smirnov Test — Kolmogorov-Smirnov The test statistic in the Kolmogorov-Smirnov test is very easy, it is just the maximum vertical distance between the empirical cumulative distribution functions of the two samples. The empirical cumulative distribution of a sample is the proportion of the sample values that are less than or equal to a given value. One-Sample Kolmogorov-Smirnov goodness-of-fit test ... Oct 02, 2018 · The Kolmogorov-Smirnov (K-S) test is a goodness-of-fit measure for continuous scaled data. It tests whether the observations could reasonably have come from the specified distribution, such as the normal distribution (or poisson, uniform, or exponential distribution, etc.), so it most frequently is used to test for the assumption of univariate normality.
