In this paper, we study the possibility of using linear pair models with parameters in the form of linear operators matrices of a two-dimensional vector space in practice. A detailed description of these models, a method for estimating them, and a forecasting algorithm for them are given. To automate the process of constructing such models using the Gretl econometric package, a special script was developed that modeled the freight turnover of Russian railway transport and extrapolated its future and past values. For certain sample sizes, the resulting models turned out to be much more adequate than conventional paired linear regression models. On the basis of the study, the sample sizes were established for which it is advisable to build linear pair models with parameters in the form of linear operators matrices of a two-dimensional vector space.
