The econometric analysis of GDP per capita in the Russian Federation is being given. The number of the departured people from the Russian Federation, nominal average charged wages and exports volume are used as the exogenous variety. The received model of the multiple linear regression is being studied for quality.

Keywords: gross domestic product, GDP per capita, econometrics analysis, multiple linear regression model, endogenous variety, exogenous variety, heteroskedasticity

This article deals with the carrying out of econometric analysis by means of panel data models (pooled model, fixed effects model) of the volume of innovative goods, works and services in the Russian Federation (RF) from 2010 up to 2014 years. The dependence has been revealed between the volume of innovative goods, works, services and such explanatory factors as the number of personnel involved in scientific research and development; internal expenses for the scientific researched and development of the Russian Federation; used advanced manufacturing technologies; coefficient of inventive activity; innovation activity of organizations.

Keywords: econometric analysis, panel data, innovation, science, integrated model of panel data (pooled model), a model of panel data with fixed effects (fixed effects model)

An econometric model, expressed as a system of simultaneous equations, must be constructed to analyze the crop production dependence on the investments amount, used fertilizer, number of tractors and sown arias.

Keywords: crop production, agriculture, linear multiple regression, the system of simultaneous equations, determination coefficient, endogenous variable.

One of the most important problems of demographic statistics is studying of natural movement of the population. One of the major indicators of studying the natural movement is the rate of birth. In this article econometric models of linear regression of dependence of birth rate of the population from security with the medical personnel and expenses on health care, physical culture and sport were constructed.The importance of the constructed models and their parameters is checked, the forecast becomes.
