摘要
本文在分析数据序列性质与GM(1,1)模型关系的基础上,指出了不同情况下的GM(1,1)建模方法,提出了大M改进建模法,扩充了予测范围,提高了适用性。
In this paper, on the basis of analyzing the relationship between the properties of the original datum series and GM(I,I) model, the modellings for GM(1,1) in different cases are pointed out, and the modelling of infinite constant M for GM(1,1) is put forward. This expands the predicting scope of the model, and raises its practicality.
