Distribution kolmogorov smirnov
WebOct 26, 2011 · The distribution is non-standard, however, it can be tabulated and used with any location and scale of the underlying distribution. The Kolmogorov-Smirnov test for the normal distribution with estimated location and scale is also called the Lilliefors test. It is now available in statsmodels, with approximate p-values for the relevant decision ... WebKolmogorov-Smirnov test in R. I tried to use the Kolmogorov-Smirnov test to test normality of a sample. This is a small simple example of what I do: One-sample Kolmogorov-Smirnov test data: x D = 0.3427, p-value < 2.2e-16 alternative hypothesis: two-sided. The p-value is very low whereas the test should accept the null-hypothesis.

For avoiding confusion, there's 2 Kolmogorov-Smirnov tests: there's … WebThe distribution of D n can be calculated (see Kolmogorov Distribution), but for our purposes now the important aspect of this distribution is the table of critical values. These can be found in the Kolmogorov-Smirnov Table. If D n,α is the critical value from the table, then P(D n ≤ D n,α) = 1 – α.

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’ (default), ‘less’ or ‘greater’.
