| 摘 要： | 在研究非等间距GM（1,1）模型的基础上,发现当原始数据递增时,拟合和预测的结果较好;当原始数据递时,拟合和预测的结果误差较大。因此,将递减的原始数据转换为递增的数据可以提高拟合和预测的精度,该文采用的方法是对原始数据进行倒数运算。实例结果显示,该方法能有效地拟合和预测系统的发展,为灰色提高预测精度提供了一个有效的方法。

| Abstract: | Based on the unequal interval zone,when the original data were increased with the time,the fitting and predictive data were higher.When the original data were decreased with the time,the fitting and predictive data were relative lower.So if the decreasing data was changed into increasing data,the accuracy would increase.In the paper,the reciprocal operation was adopted on the original data.The examples showed the method could fit and predict the system development which provided a new way for the data mining. |
