    摘 要:目的 重复观测数据存在自相关性常导致一元方差分析的误用，探讨一元方差分析两个假定条件的检验. 方法 通过标准正交对比变换克服数据间的自相关性，应用似然比统计量进行假定条件的检验. 结果 给出了重复观测数据一元方差分析的假定条件检验方法，并用软件REP得以实现. 结论 只有满足假定条件，才可以保证重复观测资料单变量方差分析的有效性.

    Abstract:AIM To explore the tests for two presuppositions concerning the validity of the univariate analysis of variance with repeated measures.METHODS The authors intro-duced orthonormal contrast transformation to avoid auto-cor-relation，and proposed the tests of presuppositions by likeli-hood ratio statistics.RESULTS Hypothesis tests for the presuppositions of the univariate ANOVA with repeated mea-sures were given ......
