The next step in the correlation analysis is to calculate the link equation (regression) , which is carried out step by step. Initially, one factor that is most likely to affect the final score is the second, third, and so on. In each step, the relationships of correlation coefficients, correlation coefficients ( R ), determinates ( D ), F- immunosabat (Fisher's criterion), standard case ( ? ) , Which help to estimate the reliability of the bond equation and others. At each step, their value is compared to the previous one. The smaller the coefficient of correlation, the more determinative and the greater the standard of Fischer criterion, the closer the equation, which represents the link between the indicators studied. If the subsequent factor does not improve the link value, this should be abandoned, meaning that the point should be stopped at the optimal stage.

In each step, the comparison of the results is entirely the fifth row, and it can be called a five-factor model.
