- (Contens №2 2020)
- ... Findings. Economic and mathematical modeling of the activity of the JSC Inhulets Mining and Processing Combine showed that the presence of multicollinearity when applying a multifactor regression model leads to a distortion of the obtained results, which reduces the practical value of the model. The application of the parametrization method made it possible to reduce the influence of multicollinearity by providing parametric representations of the economic-mathematical model of holding the real economic process. The application of the parameterization method makes it easier to construct an economic-mathematical model in the form of regression equations, to reduce the negative impact of multicollinearity in the implementation and meaningful analysis of features of economic and mathematical modeling using multivariate regression equations. ...
