通过对GM(1,1)模型的原始形式的分析,得到与之等价的差分方程,然后把差分方程连续化得到微分方程,并定义为GM(1,1)模型的白化方程,最后通过实例验证了新模型的有效性.
By analyzing the original form of GM (1,1) model, we obtained an equivalent difference equations matched with the differential equations, and then continuous differential equations was defined as the whitenization equation of GM (1,1) model. At last an examples was given to verify the new model's efficiency.
