摘要
本文通过论证序列的GM(1,1)模型计算值与原始序列的初值无关,讨论仅有三个数据构成的序列的灰色建模问题,得出可进行灰色建模的最少数据数为3的结论.
By proving that calculated values from GM(1. 1) model of sequence are independent of the initial value of the sequence, the grey modelling problem of the sequence with three initial values was discussed in this paper. We obtain the conclusion that the minimal number of values in the sequence is three, which is required by GM(1,1) modelling in Grey System Theory.
