摘要
灰色系统理论通过序列的生成和开发,致力于现实规律的探讨,而数理统计则致力于统计历史规律的研究.结合灰色系统与经典因子分析的优点,提出一种新的模型,即灰因子分析,并利用面向对象程序设计的方法进行了系统实现,对结果所做的分析对比表明效果显著.最后将该方法应用到实例中,实验结果显示,该方法对具有时间序列的研究起到了推动的作用.
Factor analysis is one of the ways of the classical statistics, which can only give the distribution and variance. It can＇t reflect the character of varying data, and can＇t resolve the problem of the time series. In order to make up the deficiency that it can＇ t solve the time series data, because the grey system data have time series characteristics, that is grey system theory is devoted to the discussion of real order, while the classical statistics is devoted to counting the research of the historical orders, it combines the grey system method with the factor analysis,forming a new model, i. e. grey factor analysis. And it uses oriented object programming method to implement the system, contrasting the results, and the result is prominent. Finally, it applies this method to the example. There is certain promotion to the research for the time series that this paper puts forward.
