灰色建模中数据缺失值处理方法探讨

为解决在利用灰色理论建模中,出现的数据缺失问题,本文提出综合利用SPSS软件的缺失值处理模块和稳健估计模块,针对数据的缺失机制进行处理的方法。使用该方法对缺失数据进行处理,以保证模型能够正常进行数据拟合。本文还利用了SPSS软件对某一实例中的缺失值进行了估计,并对缺失值填充后的结果进行了评价。

On the Treatment of Data Missing in Building Model with Grey Theory

In order to solve the problem of data missing in building model with grey theory, the article proposes a method of dealing with missing mechanism of data by using the synthesis of robust estimation computing modules and missing data of SPSS processing module. Handling missing data by the method en- sure that models can normally fit data. It estimates missing data in one instance, and evaluates the result of fillin~ the missin~ data to achieve the objective, and accurate results.
