GM(1,1)模型简化算法及其在噪声影响预测中的应用

SIMPLIFIED CALCULATION OF GM (1.1) MODEL AND ITS APPLICATION TO NOISE IMPACT FORECAST

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.
