摘 要: | 通过对灰色关联度模型机理进行分析,引入符号函数重定关联系数,并给出了一种新的关联度定义方法.改进后的关联度模型能够反映时间序列的正、负相关关系.实例验证表明,改进的灰色关联度能够更真实地反映时间序列曲线的关联程度,所得关联分析结果客观可靠,并且易于上机实现.

Abstract: | In the existing mechanism on the basis of the analysis of the grey correlation model, through introducing the sign function reset correlation coefficient, we defined a new correlation method. The improved correlation model can re- fleet the positive and negative correlation between the time series. Example shows that the grey correlation degree of im- provement can be more truly reflect the connection degree of time sequence curve, the correlation analysis results objective and reliable, and easy to computer implementation. |
