WebMay 11, 2014 · 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’ (default), ‘less’ or ‘greater’.
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. tamil proverbs about liesWebFor a numeric array or typed array x, a Kolmogorov-Smirnov goodness-of-fit is computed for the null hypothesis that the values of x come from the distribution specified by y. y can be either a string with the name of the distribution to test against, or a function. tamil pushpa movie downloadWebAug 2, 2014 · Stephens has tabulated quantiles for the modified statistic.
