摘要
利用矩阵的广义影响函数和广义Ｃｏｏｋ统计量研究了具有Ｒａｏ的简单协方差结构的生长曲线模型的局部影响问题．得出了各种扰动形式下参数估计的局部影响度量．并通过实例，说明了该方法有效可行，有一定的实用价值．
Generalired influence function and generalired Cook distance were used to study local influence of maximum likelihood estimation in the growth curve model with an unknown Rao's simple covariance structure.Under the various kind of perturbation schemes.the local diagnostics of parameter estimates were obtained and an example was used for illustration.
