• Kolmogorov-Smirnov test • D’Agostino test. Q-Q plots display the observed values against normally . distributed data (represented by the line). Normally distributed data fall along the line. Graphical methods are typically not very useful when the sample size is small. This is a histogram of the last example. These data do not ‘look’ normal, but they are not statistically different

Specifically, the Kolmogorov–Smirnov test is used to test the goodness of fit of a given set of data to a theoretical distribution, making this a one-sample test. In contrast, the Smirnov test is a two-sample test, used to determine if two samples appear to follow the same distribution. The intuition behind the two tests is the same, however, in that both compare cumulative distribution

In the Kolmogorov-Smirnov table, the critical value of D increases as alpha (1-P) decreases for a given N. This would imply that if a sample K-S statistic is < the critical D value at say the .05 level, then it must also be < the critical D value at the .01 level. This does not seem logical to me – …

ksmirnov — Kolmogorov–Smirnov equality-of-distributions test
The Kolmogorov-Smirnov (KS) test is a well known non-parametric method for distinguishing between distributions, and, as such, a perfect candidate and an interesting competitor to the (already much discussed) mutual information (MI) based attacks. However, the side-channel distinguisher based on the KS test statistic has received only cursory evaluation so far, which is the gap we narrow here
The Kolmogorov-Smirnov test relies pretty fundamentally on the ordering of observations by distribution. The logic is that if the two underlying distributions are the same, then—dependent on sample sizes—the ordering should be pretty well shuffled between the two.
Perform the Kolmogorov-Smirnov test for goodness of fit. This performs a test of the distribution G(x) of an observed random variable against a given distribution F(x). Under the null hypothesis the two distributions are identical, G(x)=F(x). The alternative hypothesis can be either ‘two-sided
