摘要
用样条函数对GM(2,1)模型的残差序列进行插值拟合,然后作用于二阶线性微分方程,并以此修正原模型,得到一种新的预测模型GSM(2,1)的数值解。
A new numerical solution of predication mode1 GSM (2, 1 ) can be gained by use of spline function to fit the residue order of GM (2,1)model,and it acts on the second-order linear differential equation and corrects the original model.
