协方差分析的SAS实现方法

The Application of SAS in Covariance Analysis

协方差分析是将方差分析和回归分析综合起来的一种统计方法,在科学研究中有着十分广泛的应用。本文通过苹果树实验数据的方差分析与协方差分析结果差异的比较,探讨了协方差分析方法在果树实验中的应用,同时还阐明了其SAS实施过程。

Covariance analysis is a statistical method with variance analysis and regression analysis synthesized.The paper discusses the application of covar iance analysis in apple experiment by the comparison of result's difference of v ariance analysis and covariance analysis. Meanwhile,the course of SAS achievemen t is expounded completely.
