混合效应模型在系统分组资料中的应用及SAS实现

Mixed Model in the Hierarchical Classification Datas and Implementation of SAS

目的探讨系统分组资料的混合效应模型的建模及SAS程序实现。方法以系统分组资料例证混合效应模型的SASMIXED实现过程,并与传统的广义线性模型结果作比较。结果该实例显示SAS混合效应模型结果与广义线性结果一致。结论SASMIXED可以灵活地拟合和分析系统分组资料。

Objective To investigate the mixed model in bierarchical classification datas and implementing with mixed model in SAS. Methods Hierarchical classification datas exemplify the mixed model using procedure mixed,and compared with traditional general linear model. Results The example shows the same result between the SAS mixed model and the general linear model. Conclusion SAS MIXED can flexibly fit and analysis hierarchical classification datas.
