多元析因设计的方差分析及其SAS程序实现

[目的]针对医学研究中常见的多元析因设计方差分析存在的问题,给予统计软件技术上的支持。[方法]利用SAS统计软件包,结合实例,编写程序,计算相应的统计量。[结果]运用SAS程序对实例数据由单因素分析及多因素分析,得出实例数据中的两处理因素及其交互作用均有统计学意义。[结论]研究临床中多元析因设计利用SAS软件包进行统计分析的途径,为类似问题的解决提供了参考。

MULTIVARIATE FACTORIAL VARIANCE ANALYSIS AND EXAMPLES OF SAS PROGRAM

[Objective] To explore a SAS progrme,which is able to solve the problem of multivariate factorial variance analysis during medical study.[Methods] An example and corresponding statistics were analyzed and calculated using SAS program.[Results] Main effect and interaction of two factors in the example were significant statistically both in univariate analysis and multivariate analysis.[Conclusion] The problem existing multivariate factorial variance analysis can be solved effectively by using the procedure o...
