This paper proposes a hybrid model for predicting household over-indebtedness, which outperforms reference models in correctly classifying indebted individuals. This model provides an innovative understanding of household over-indebtedness, which is crucial for preventing excessive indebtedness and maintaining financial stability.
The increase in debt levels of families in different parts of the world has drawn the attention of organizations dedicated to the prevention of financial risk and has highlighted the need to develop early detection methods for over-indebtedness. In this paper, we propose a hybrid model of the adaptive neural fuzzy inference system (ANFIS) and Probit model for the prediction of household over-indebtedness. The proposed model is compared with Probit, artificial neural networks (ANN), classification and regression trees (CART), random forest (RF) and support vector machine (SVM) models. The most relevant parameters for the performance of each model are optimized, and we address data balance problems through the synthetic minority over-sampling technique (SMOTE). We use data obtained from the Financial Household Survey of the Central Bank of Chile. The results show that the proposed model performs significantly better than the reference models in terms of the correct classification of indebted individuals. Consequently, this model provides an innovative understanding of household over-indebtedness, which can be useful for different governmental entities focused on preventing excessive indebtedness and maintaining financial stability.
