Abstract

As the financial market becomes larger, the loss increases due to the failure of the credit risk managements from the poor management of the customer information or poor decision-making. Thus, the credit risk management also becomes more important and it is essential to develop a credit scoring model, which is a fundamental tool used to minimize the credit risk. Credit scoring models have been studied and developed only for binary target variables. In this paper, we consider other types of target variables such as ordinal multinomial data or longitudinal binary data and suggest credit scoring models. We then apply our developed models to real data and random data, and investigate their performance through Kolmogorov-Smirnov statistic.

금융시장의 규모가 점점 더 커짐에 따라 고객정보 관리 미숙 또는 부실한 의사결정, 즉 신용 리스크 관리 실패로 인한 손실이 막대하게 증가하고 있다. 따라서 신용 리스크 관리가 점차 더 중요해지고, 이런 신용 리스크를 최소화하는 기본적인 도구인 신용 평점 모형이 절실히 요구된다. 신용평점 모형은 주로 이항형 목표변수만 이용하여 개발 연구되었다. 본 논문에서는 순서형 다항 자료 또는 경시적 이항 자료 같은 다른 형태의 목표 변수를 고려한 신용평점 모형구축 방법을 제시한다. 그 개발된 모형을 실제 자료와 랜덤화한 자료에 적용하여 Kolmogorov-Smirnov 통계량으로 비교 분석한다.
