Since DW=1.96 there is no autocorrelation(---)-regression equation defined

(---) 
is reliable and adequate, this (---)-regression equation is exponentiated to get rid of the logarithm, 
and the (---)-regression equation becomes:

If we give an economic interpretation to this (--)-regression equation, it was found that if 
production costs and energy consumption in the enterprise are reduced by 100%, the efficiency of 
enterprise management will increase by 0.014% and 0.02%, respectively. However, if the raw 
material consumption is increased by 100%, the management efficiency is found to increase by 
0.47%. In turn, it is appropriate to provide the enterprise with raw materials as much as possible 
while promoting the relations of economic cooperation in the management of the enterprise, and 
in this regard, any available opportunity should be used. 
Now we will carry out an econometric analysis of the influence of factors such as 
production costs - X1, energy consumption - X2 and raw material consumption - X3 on the change 
of management efficiency - Y, calculated using the statistical data of "Koqon oil-oil" JSC for the 
years 2008-2020. First, we can check the correlation coefficient between these factors and the 
resulting factor (strong or weak) by conducting econometric analyzes and the order of selection of 
factors (Table 3).
