Expert evaluation of economic information in the construction of the econometric model

The article deals with the problem of constructing a dynamic econometric model of the gross harvest of fruit and berry crops with the possibility of using them to determine the parameters of the method of least squares. One of the necessary conditions for its use is the constancy of the variance of the residuals of the model. The article verifies the integrity of the heteroscedasticity of the residues on the basis of the Holfeld-Kwanda parametric test.
