4) additive index
累加指数
1.

5) cumulative number
累加次数
1.
In accordance with analysis of various examples, this paper points out that so far as same primitive sequence is concerned, forecasting value of GM(1,1) enlarges when the calculating null point rises, and the second term of the new sequence decreases, and cumulative number increases.
根据各种应用实例的分析,指出对于同一原始序列来说,当计算零点升高、新序列的第二项减小或累加次数增多时,GM(1,1)模型的预测值增大,同时指出这些问题是由GM(1,1)模型本身的特点所决定的。
