Based on the result of Coefficient of Determination (Adjusted R2), it shows that OER, NPL, and CAR have an effect of 62.2% on NIM whereas the rest (100% - 62.2% = 37.8%) is influenced by other reasons outside the model. Based on the result of the F Test, it is found that the OER, NPL, and CAR variables simultaneously have a significant effect on NIM.
