Cross-correlation analysis of the productivity of sugar beets and factors, that it is formed

     Important description of regressive model is a relative effect of influence of factor of x on a result in is a coefficient of elasticity: 

     He shows, on how many percents a result changes in middle у from  the change of factor х on 1%.

      - coefficient - shows on how many standard deviations an effective sign will change at the change of factor on 1 standard deviation: 

     

 

     Utillizing information of project task, will expect basic indexes, which characterize the crowd conditions of connection between the productivity of grain-crops, quality of soil and bringing of mineral fertilizers. Utillizing auxiliary information expected in a table 7 will make the system of equalizations: 

     

     Will divide each of three equalizations on a coefficient at :

     

     Will take away from the first equalization second and third:

     

     Will divide each of three equalizations on a coefficient at :

     

     Will take away from the first equalization second:

       

     

     

     

     Expecting the coefficients of regression we can set, as far as will change hopes of milk at the change of the proper factor on unit on condition that the second factor, plugged in equalization, is at middle level. So а₁=0,73 shows that at the middle dose of output of calves of improvement of charges of forages on one mark will be instrumental in growth of milk yield on 0,73 c.

     The increase of output of calves on a 1 head at the middle expense of forages will provide the increase of yield on 0,161 c.

     Utillizing these tables  will expect indexes which determine the crowd conditions of connection .

Conclusions 

     The purpose of this work was research and analysis of data about hopes of milk in the aggregate of economies, to find the middle indexes of production, conduct grouping of economies after different signs, to define basic internal conformities to the law of process of growing of sugar beets, to find out the measure of influence on hopes of such factors as charges of forages and output of calves in general. During implementation works were to utillize the basic methods of statistical research and theoretical positions of science are applied in practice.

Theoretical part of work includes the study of object, tasks and system of indexes of statistics of stock-raising, except for it familiarized with basic normative documents, which regulate a sphere, principles and tasks activity of statistics, in Ukraine.

     Conducting calculations we can assert that the middle level of yield on a cow for aggregates makes 36,91 c at the same time he hesitates on ± 2,258c or on 6,2% in relation to a middle level, middle level of the utillized forages makes 39,09c.f.un and he in same queue hesitates on ±2,06c.f.un or на 5,3% in relation to a middle level, also at to the middle output of calves for aggregates in a size  93,7 chairmen it hesitates on ±2,08 marks or on 2,2% in relation to a middle level.

     In addition building two cross-correlation models we can mark that hopes on a cow depends on the expense of forages on 57,76%, and other 42,24% it is other невраховані factors, and in other case of hopes  depends on the output of calves on 35,76%, and other 62,24% it is other невраховані factors.
