【摘要】 在对非等间距序列建模时,考虑到序列本身的特点,结合GM(1,1)模型的建模过程,提出了一种对非等间距序列建立变参数GM(1,1)模型的方法,并将其应用于具体实例进行分析,计算结果表明本文提出的方法具有较高的精度,从而为解决非等间距序列的拟合及预测问题提供了一种比较好的思路.更多还原

【Abstract】 Combined with the process of GM(1,1) Mode,considering the characteristic of sequence when modeling on non-equidistant sequence,a approach for establishing GM(1,1) Model with Variational Parameter for non-equidistant sequence are presented.Calculating about concrete example suggests that the approach raised has better precision,and provides a feasible method for the fitting and forecasting for non-equidistant sequence.更多还原
