基于分位数回归模型的债务违约损失预测
摘要
Abstract
Existing most studies about default loss usually focus on the average forecast, but the mean cannot effectively depict the distribution of the default loss rate, especially, as for non-normal extreme deflection and bimodal characteristics. This paper depicts perfectlythe distribution of the default loss rate using conditional quantile regression model, which is a new perspective to quantify the impact on default loss rate model from covariate. The comparative test results among several models show that quantile regression model in estimating the default loss rate has a more significant advantage than all kinds of mean regression model. The modeling approach suggested in this paper can be an alternative method used to estimate the default loss rate for commercial banks and other lending institutions.关键词
