A statistical test for goodness of fit. The essence of such a test is the following. Let be independent identically-distributed random variables whose distribution function is unknown. Then the problem of statistically testing the hypothesis that for some given distribution function is called a problem of testing goodness of fit. For example, if is a continuous distribution function, then as a goodness-of-fit test for testing one can use the Kolmogorov test.
