Comments

The test is used to check whether a sample has the specified distribution. For example, we test a hypothesis that the sample has a normal distribution. A small probability value means deviation of the normality hypothesis. For a sample having normal distribution, probability value tends to 1.

This test can also be applied in case of two samples. In this case, the first sample distribution is compared with the second sample distribution, and the decision is made whether the samples have the same distribution or not. In case of two samples, distribution type and parameters need to be defined.

Properties
