摘要
在D.D.C法的基础上,对门限自回归模型中门限值、滞后步长、各门限区间模型阶数利用正交设计方法寻优,计算工作量锐减,却可得到精度较高的预报模型。
In this article, the methods of orthogonal designs for magorizedly optimizing the threshold value in the threshold auto-regression model, the lagging step-length and the order of threshold interval model are presented. These method are based on the D. D. C way. It can help us reduce lots of work load and gain a very accurate forecast model.
