In the enterprise management the important components are the analysis and the activity planning and the analysis process is combined with the forecasting of the progress of the various processes. For solving this class of problems the economical and mathematical methods became widespread, these methods allow to model the complex situations, to state their value, to predict the processes, to plan the activities, to identify the patterns, to uncover the cause-and-effect relations between the objects and the phenomena. The authors present one of the approaches in the forecasting the process of making the administrative decisions.

In the paper approach to developing model that describes relation between core interest rate of regulatory bodies and parameters related to investment in fixed capital in country’s economy is proposed. As the base for creating model open data on Republic of Uzbekistan and USA were used. Good degree of conformity of model’s calculations and real data was revealed.

This article discusses the least squares method and demonstrates its application in Wolfram Mathematica. The steps for constructing an approximating function are described, and the results and the resulting functions are visualized.
