混合模型的假设检验

Statistics test of linear mixed model

在带有区组效应的线性混合模型中 ,如何判断随机区组效应的存在性 ;在区组效应存在的情况下 ,如何对多项式效应进行检验是本文讨论的主要问题 .本文通过对区组内分析和联合分析 。

In many experimental situations,a response surface design is divided into several blocks to control an extraneous source of variation.Then the linear mixed models are discussed.In this paper,the distribution of test statistics for the fixed effects and the test methold of blocks effects are given.
