### Development of the Integrated RJD Efficiency Forecasting Method
When the linear discriminant analysis was used on the Bsh site, 31 of 33 (94%) objects with the relative liquid production increment of less than 5 times were correctly

recognized, and 30 of 35 (86%) objects with the increment of more than 5 times were correctly recognized. The reliability of the models is due to the high training dataset classification correctness rate (83 to 97%) and the high values of the canonical correlation coefficients (0.71-0.79). For the T site, the linear discriminant function was as follows (2):  
\[\text{Z}=-0.39\cdot\text{q}_{\text{liq}}+0.27\cdot\text{P}_{\text{res}}-0.102 \cdot\text{h}_{\text{av}}+0.26\cdot\phi+0.069\cdot\text{S}-6.48;\ \text{R}=0.79 \tag{2}\]  
For the T site, 28 of 33 (85%) objects with the relative liquid production increment of less than 4 times were correctly recognized and 31 of 32 (97%) objects with an increment rate of more than 4 times were correctly recognized.
