ASSESSMENT AND ANALYSIS OF THE DYNAMICS OF EFFICIENCY OF SUNFLOWER IN RUSSIA FD
Goal. Described using histograms accumulation, charts, bubble charts volumetric changes of gross yield, yield and sunflower sowing areas in the federal districts of Russia during the past 5 years. Factor analysis of the effect of yield and acreage to changes in gross collection. Built equation for forecasting the gross sunflower harvest. Methods. We used the methods of descriptive statistics, visualization, factor analysis, correlation and regression analysis. Results. To identify differences between the federal districts were summarized figures for gross harvest, yield and acreage of sunflower in the federal districts of Russia during the past 5 years. It is possible to trace the trend of these changes in the indices of all FD (as well as the relative position of FD), not only for one year, but for the last 5 years at the same time with the help of histograms and graphs accumulation. Bubble charts clearly demonstrated the interdependence of all three indicators that statistical calculations has been confirmed in the future. Factor analysis showed the importance of the influence of yield and acreage gross sunflower seeds in federal districts of Russia. Conclusion. Using the methods of descriptive statistics, visualization, factor analysis, correlation and regression analysis demonstrated their great potential for the evaluation and analysis of the dynamics of efficiency of sunflower production. On the basis of descriptive statistics and visualization techniques have been investigated location of each FD in the development of culture as the data over time and relative to other FD. It has been made appropriate recommendations on the priorities for each DOF. On the basis of factor analysis concluded that sunflower yield was made in the Federal District is given a lot of attention, which is not fully to the increase in acreage. The calculated multiple regression equation allows you to make forecasts of gross collection and suggests that the productivity effect on the gross yield is much more significant than the impact of acreage.
