缺失原始数据的单因素方差分析方法研究

Research on the One Way Analysis of Variance with the Loss of Original Data

对缺失原始数据的数据资料进行了方差分析。从方差分析的基本原理入手,对基本统计数据进行反向推理,得到处理间和误差项的各项离差平方和、自由度以及均方,从而可以实现缺失原始数据下的方差分析,并编写了SAS程序予以实现整个计算和方差分析过程。

We completed the analysis of variance without original data.Based on principle of analysis of variance and basic statistics,it was carried out mathematic deduction to obtain sum of square,degree of freedom and mean square of errors and treatments,so analysis of variance could be accomplished in the condition of loss original data.In the end,SAS procedure was programmed to realize the whole process of calculation.
