SAS聚类分析过程在农业试验统计分析中的应用

Application of Cluster Analysis from SAS System in the Process of Agricultural Research and Statistics Analysis

为帮助农业工作人员利用SAS软件分析农业试验数据,通过对鸢尾花数据的研究,给出了聚类分析程序,通过聚类树形图表示出分类结果;比较各聚类方法,如:AVE,MED,SIN,EML,MCQ与WAR,得出类间距的计算方法,利用统计量的方法比直接观察数据的方法准确。同时对SAS程序的各项参数含义及其可实现的功能作了详细说明。

The writer＇s main purpose is to help the staff members who need SAS to analyses data. Clustering analyse applications in testing statistic analysis in the agriculture are introduced. The writers also introduce detailed description of parametric of SAS procedure with an example.
