In this paper we discuss the tests for homogeneity of variances and correlation coefficients in longitudinal data model with exponential correlation covariance structure and obtain several score test statistics. The glucose data is used to illustrate our results.

本文针对具有指数相关协方差结构的纵向数据模型，研究了方差齐性和相关系数齐性的检验，得到了检验的score统计量，并对葡萄糖数据进行了分析。

Lin and Wei considered the tests for homogeneity of within-individual variances and between-individual autocorrelation coefficients of nonlinear models with AR(1) errors based on longitudinal data.

对具有AR(1)误差的非线性纵向数据模型，林金官和韦博成讨论了其方差和相关系数的齐性检验。

Resul ts showed that material filling has inhomogeneity and time sequence, material r heological direction is mainly on longitude, and lateral rheology makes filling tend to homogeneousness.

结果表明，凸向模压成型时物料充填具有不均匀性和压缩时序性。物料流变以纵向为主，横向流变使充填趋于均匀。

In the analysis of longitudinal data, when the clusters size are random, it is still a conventional hypothesis that random effects should have homoscedasticity, Otherwise statistical inference would be more difficult.

类似与固定组容量模型，在组容量随机情况下的纵向数据分析中，假设随机效应方差齐性也是值得怀疑的，需要用统计的方法予以确认。
