coefficient shows, on how many sizes of mean square deviations the productive sign at increase changes factorial on 1 mean square deviation. The more i on the module at i-ohm a factor, the is stronger influence of this factorial sign on change of a productive sign, and vice versa.
At rather uniform or normal distribution of units of the studied set apply groups with equal intervals. The number of groups on which it is expedient to dismember statistical set, is determined by a formula:
the size accepting values between 0 and For interpretation of the direction of communication between variables look at signs (plus or minus) of regression coefficients or B-coefficients. If the B-coefficient is positive, communication of this variable with a dependent variable is positive; if the B-coefficient is negative, and communication has negative character. Of course, if the B-coefficient is equal 0, communication between variables is absent. At R=1 – there is a functional communication.
Scientific basis of the report is the group of the data obtained as a result of statistical supervision. The group provides formation of uniform groups on the basis of division of statistical set into parts or associations of the studied units of group on signs, essential to them.
The group on the level of labor input of production of grain crops showed that with growth of average labor input such indicators as level of marketability of grain, prime cost of 1 c and profit grow. As for other indicators, a certain tendency to increase or reduction it is not observed.
In statistics of finance of the enterprises (organizations) the system of the indicators reflecting a financial position of economic entities, receipt, distribution and nature of use of money, the sizes and structure of debt including overdue, etc. is applied.
On analytical expression of communication can be linear and nonlinear. Linear communication is expressed mathematically by the linear equation, and graphically – a straight line. Nonlinear communication is mathematically expressed by the equation of a parabola, a hyperbole, etc., and graphically – a curve of the corresponding look.
Thus, on the module 5 = 0,36078 is of the most great importance, that is costs of 1 hectare of crops of grain crops have the greatest influence on change of profit per 1 c grain; productivity grain (has the weakest impact on receiving profit to 4 = 0,088
Financial resources are money (own and are attracted economic entities, being at their disposal and intended for implementation of financial obligations and implementation of expenses for production.
At group on quantitative signs of group can have both equal, and unequal intervals. Unequal intervals are applied when change of a grouping sign on units of population happens unevenly and in considerable limits.
The given calculations showed that at increase in a fondoobespechennost of economy by 1% the profit per 1 c of grain will decrease by 0,219%; at increase in labor input of production of grain the profit got on 1 c will decrease by 0,155%; the increase in compensation of workers by 1% will cause reduction of profit per 1 c of grain for 0,086%; increase of productivity of grain crops will also negatively be reflected in the got profit on 1 c, – it will decrease by 0,044%; the increase in costs of 1 hectare of crops will lower profit by 0,493%.
In groups on a qualitative sign the closed and open intervals are applied. If the lower and top borders of intervals have digital values, intervals are considered as the closed. If the lower bound of the first interval and the upper bound of the last interval are not designated, the group is considered with open intervals (.
The group on the level of labor input of production of grain crops showed that with growth of average labor input such indicators as level of marketability of grain, prime cost of 1 c and profit grow. As for other indicators, a certain tendency to increase or reduction it is not observed. The greatest productivity is noted in the I group, the smallest – in the II group; the greatest level of profitability is observed in the I group, and the smallest – in
