摘要
针对门限自回归模型在模型识别方面的不足,提出了逐步门限自回归模型,并同时给出了该模型的一种建模方案。数值实例表明,逐步门限自回归模型在模拟和预报稳定上比一般门限自回归模型有一定程度的提高。
The designing of a stepwise threshold autoregressive model is presented in this paper to improve the ordinary threshold autoregressive model that is imperfect in recognition. Numerical experiments show that the designed model is better to some extent.
