GM(1,1)模型的关联度检验分析

Relational Coefficient Test Analysis for GM(1,1)

讨论了灰色关联分析中存在不合理下限 ,提出了对不合理下限的调整方法 ,由此得出关联度分析不适合对GM( 1,1)模型进行检验 。

This paper discussed the irrational lower limit in grey relational analysis, and gave a method for adjusting irrational lower limit. Based on the discussion, the relational coefficient analysis is not fit for GM(1,1) test, and exist default in un unit process for the same unit sequences.
