Statistical models are most predictive and robust when the historical data used to build the model covers sufficient representation from the population. A financial organization uses a scoring model, developed with historical data, to determine if a consumer should be granted a line of credit for which they apply. When the existing model is too old or the applicant population has changed, a new model is to be developed, but the range of historical data, essential to the predictive model development, does not include the entire applicant population because of the declines. A technique called reject inference is typically used to infer the unknown performance of the reject population as a new scoring model is developed. This paper explores several techniques that have been published, selects the most promising technique, and introduces an adjustment to the existing technique.
