The analytical method used consists of multiple regression analysis , the classical assumption , hypothesis testing ( t test and F test ) and test the coefficient of determination . From the results of this study concluded that based on regression analysis obtained the following equation : Y = 6.342 + 0.008 + 0.044 XI X2 - 1.176 X3 . In the classical assumption test found a problem in the autocorrelation test , whereas the normality test, multicollinearity and heteroscedasticity test there is a problem in the model . Based on the hypothesis testing , the F test is known that jointly ( simultaneously ) variable CAR , NIM and LDR significant effect on ROA . While the t test ( partial testing ) , variable CAR and NIM has no effect on ROA . While variable LDR dominant and significant positive effect on ROA
