基于似然比检验的VaR回测研究
VaR Back-test Based on Likelihood Ratio Test
摘要
Abstract
Based on likelihood ratio test theory, this paper makes a study on Value-at-Risk (VaR) back-testing with the general subject to Pascal distribution, geometric distribution and binomial distribution, and puts forward the average first failure times test and the average failure rate test, leading to the result that the back-testing method proposed by Kupiec(1995)is just a special case of the research conclusion of this paper. Finally, the numerical calculation verifies that the method proposed in the paper has higher efficacy, and to a certain extent improves the accuracy of VaR prediction test.关键词
