Overview of the consent criteria of the "Statistician-consultant" system

The concept of goodness-of-fit criteria was given. The criteria studied in this paper are indicated: Pearson, Kolmogorov-Smirnov, empty boxes. The stages of the methodology for conducting experiments are described. Models of dependences of the powers of the considered goodness-of-fit criteria on the level of significance, sample size, and parameter values of the tested hypotheses are constructed. Which, in turn, makes it possible to formulate recommendations to users on the choice of a goodness of fit criterion and even on the choice of some conditions for the experiments themselves in certain cases. In other cases, the constructed models also make it possible to formulate recommendations or can serve as a certain guideline for choosing a criterion.
