摘要: 应用门限模型对利率期限结构模型中漂移项的非线性性进行建模,提出门限(threshold)CKLS模型。用基于自助法(bootstrap)的广义拟似然比检验方法对门限CKLS模型进行了检验。检验结论表明:门限CKLS模型能较好的刻画利率期限结构模型中漂移项的非线性,在0.1的显著水平下优于CKLS模型。

关键词: 门限模型, CKLS模型, 非线性, 广义拟似然比检验

Abstract: The threshold model is employed to capture the nonlinearity of the drift term in the models of the term structure of interest rates. A generalized pseudo-likelihood ratio test is introduced to test the threshold CKL,S model. The results show that the threshold CKL,S model can better describe the nonlinearity of the drift term than CKL,S model at 0.1 significant level.

Key words: threshold model, CKLS model, nonlinear, the generalized pseudo-likelihood ratio test
