摘要
对GM(1,1)模型经差分形式化及今定写成直线方程形式。据最小二乘法原理。原万程的参数辨识可借助线性回归方法来实现。从而使GM(1,1)模型的应用更显普及和实用化。
GM(1. 1 ) model is written to be linear equation by way of differential formalization. The parameter identifi-cation of the former equation can be realized with the help of linear regression according to least square principle,which leads to GM(1.1)model much more significant and practical.
