摘要
提出了一种基于级比数据处理的多段灰色建模方法,详细阐述了其建模机理和建模步骤.该模型拓宽了GM(1,1)的应用范围,有效地提高了一般GM(1,1)模型的精度.文末给出了一个利用多段灰色建模方法的例子.
In this paper, multi-stage grey modeling method based on stepwise ratio data processing is proposed. First, the principle and characteristic of this model are studied. And then the steps of modeling are also described in detail .This method improves the accuracy of GM(1,1) model and widen the range of application. Finally, the method is applied in Chinese GDP modeling. The results show that the method is well effective.
