Abstract: Interpolation of time series by the sum of exponents of a function of a complex variable makes it possible to obtain a model that is not inferior to the accuracy of regression models . Although time series are interpolated by functions of a complex variable, the sum of these functions, subject to certain conditions, are real numbers. The standard MATHLAB software was used in the calculation process. The article presents an extended BRINKS model of international trade of the Visegrad Four countries (Czech Republic, Slovakia, Poland, Hungary). The numerical series characterizing the volume of exports and imports within the Visegrad Four were approximated as the sum of eight exponents, which are functions of a complex variable.
