Table 3 aboveIt can be seen from the data that all the factors in relation to the management
efficiency factor of "Koqon oil-oil" JSC with the participation of foreign investors, including
production costs - X1 (energy consumption - X2) and raw material consumption - X3

Table 4 aboveaccording to the data of the selected factors, taking into account that there is
a large difference between the indicators of the selected factors and the indicator of management
efficiency, we logarithmized the indicator of the factors. According to these values, only from the
