摘要
本文首先肯定了用数的生成方式来寻找数的规律性是一种很好的数据处理新方法。接着对灰色GM(1,1)建模的模型精度问题进行详细的讨论。否定了后验差检验方法,同时,利用数理统计常用方法对模型精度进行了比较深入的分析研究。最后,在此基础上提出了残差均值修正模型和尾部数列GM(1,1)修正模型两种新的模型修正方法。
In this paper, we deal with the precision test of the grey modelling. We point out that the test of precision in [1] was unsuitable, and the statistical tests of the error in modelling are discussed. Based on the analysis of the model modifier, two improving methods are proposed. Finally we analyze an example in detail.
