Summary: | The multiple regression analysis method is widely used to describe and investigate some processes of the regional economy and may be also used to solve an important problem of distinguishing the effects of various independent or partially dependent variables. The regression model considered includes the specification of its constituent relationships, the choice of variables included in each relation, and the definition of mathematical functions corresponding to these relations. Regression model of food expenditure with two independent variables - expenditure as a function of income and price is based upon the official quarterly averaged statistical information (2015 and 2016 years). All the data are presented in the interpolated monthly version. Regression analysis made it possible to specify the dependence of expenditure on food in the country's households on the disposable personal income and the relative price of foodstuffs, which must be taken into account when solving problems of the region's social and economic development.
