These data are included in electronic computing machines . Then, on the basis of them, the matrix of the double and the correlation coefficients, the large number of regression equations, the valuation parameters with the reliability of correlation coefficients and the equation of equations: Stuudent criterion ( T ), Fisher criterion ( F ), average error approximation ( ? ), Correlation coefficients ( R ) and determinants ( D ).

By examining the matrix of the pair and coefficients of correlation coefficients, it is possible to conclude that the circumstances under consideration are closely interconnected. The double correlation coefficient generally characterizes the relationship between the two indicators, taking into account the influence of other factors that determine the level of the final indicator.

- The data in the table (first column) indicates that all factors have a significant impact on the level of profitability. It is largely dependent on productivity, savings, product quality and productivity. With these indicators increasing , profitability (direct communication); When the length of the cash flow increases, profitability decreases (circulation).
