| Description | Lenders, such as banks and credit card companies, use credit scoring to evaluate the potential risk posed by lending money to consumers. Once a scoring model is available, it is natural to measure its quality. To evaluate the effectiveness of credit scoring models, it is possible to use quantitative indexes such as Gini index, K-S statistics, Lift, Information statistics etc. The paper deals with mentioned quality indexes, their properties and relationships. Finally, a new approach to measure power of scoring models is discussed and a new quality index is proposed. Also an application of mentioned theory on simulated data set is demonstrated. |
