APPLICATION OF THE CRITERION OF CONSISTENCY OF BEHAVIOR TO ASSESS THE ADEQUACY OF THE DISCRETE MODEL OF THE DYNAMICS OF THE IMPORT OF COMMERCIAL GOODS

Abstract: The paper presents the criterion of consistency of behavior for assessing the adequacy of mathematical models. It is based, in contrast to the criteria of adequacy traditional in regression analysis, not on the analysis of the approximation errors of the regression equation, but on the correlation of the signs of the increments for arbitrary cross pairs of observation numbers of the actual and calculated values of the dependent variable. The criterion was used to construct a linear dynamic discrete model of the dynamics of imports of trade goods in the United States from Russia. |
Keywords and phrases: the criterion of consistency of behavior, discrete model, parameter estimation, adequacy criteria.
