13 We will return to the issue in detail below, since it is crucial in our analysis. 14 If the discriminant score function can be viewed as a ‘model’ (rather than as merely the solution to an optimization problem), the coefficients would be the counterparts. The usefulness of this is in determining which particular factors would contribute most to a rejection of a credit application. 5. 12 13 14 One might question the normality assumption. But, the logistic and alternative distributions rarely bring any differences in the predictions of the model.
An equivalent procedure is to compute the ‘normalized expected profit’, E Ã ½Å ¼ EP Ã ½fE ½Åi P Ã g Â ARðP Ã Þ Ã ð1:33Þ where AR(P ) is the acceptance rate with a particular threshold probability. Obviously, AR(P Ã) increases monotonically with (P Ã). However, E[5i] | P Ã falls with P Ã. Because the acceptance rate is falling with P Ã, the profits that will be obtained from a given pool need not rise with falling P Ã. In short, a rule which decreases P Ã attracts fewer and fewer better and better loans.
