WebMar 5, 2016 · An attractive feature of this test is that the distribution of the K-S test statistic itself does not depend on the underlying cumulative distribution function being tested. Another advantage is that it is an exact test (the chi-square goodness-of-fit test depends on an adequate sample size for the approximations to be valid). WebThe chi-square where k is the number of categories (k=2 in this case, meaning 1 df) will be the square of the two-tailed one-sample proportions Z statistic and will reject exactly the same cases. (Sometimes the p-values differ a little because different approximations/statistics are used.)
