摘要
本文在多个著名的单因子利率模型的基础上,提出了一个新的一般模型,其漂移项涵盖了线性和非线性两种形式。并用广义矩方法进行参数估计,在多种指标的比较下得到了一个较好模型。此模型的漂移项为非线性形式,具有显著的均值回复效应,且利率波动对利率水平极为敏感。
In this article, a new general model is proposed in which drift can be linear and nonlineor, based on several famous single - factor interest rate models. The author estimate the parameters of different models by GMM, and obtain a better model under comparison by many indexes. This model has nonlinear drift, has significant mean - reverting effect, and the volatility is highly sensitive to interest rate level.
