重复观测资料的轮廓分析

Profile Analysis of Repeated Measures Data

对重复观测资料进行一元方差分析时，往往首先要考虑协方差阵的结构特征，而这类资料的轮廓分析则无需对协方差阵结构作出假定。本文在ＳＡＳ软件的基础上对轮廓分析的假设检验进行了讨论，并附应用实例。

In the context of repeated measurements,univariate analysis of variance often assumes that covariance matrix has a special form. But profile analysis doesn′t need to assume particular structure of covariance matrix.In this paper,on the usage of SAS software ,hypothesis tests of profile analysis are discussed,along with an example.
