UPDATING A LOGISTIC DISCRIMINATION RULE - Comparing Some Logistic Submodels in Credit-scoring

Abstract
Often a discriminant rule to predict individuals from a certain subpopulation is given, but the individuals to predict belong to another subpopulation. Two distinct approaches are usually implemented. The first approach is to apply the same discriminant rule for the two subpopulations. The second approach is to estimate a new rule for the second subpopulation. The first classical approach does not take into account differences between subpopulations. The second approach is not reliable in cases of few available individuals from the second subpopulation. In this paper we develop an intermediate approach: we get a rule to predict in the second population combining the experienced rule of the first population and the available learning sample from the second. Different models combining the first rule and the labeled sample from the second population are estimated and tested.
