具有Rao的协方差结构的增长曲线模型的局部影响分析(英文)

Influential Assessment in a Growth Curve Model with Rao's Simple Covariance Struture

利用关于矩阵的广义影响函数和广义Cook统计量来研究协方差阵为Rao的简单结构时 ,各种扰动形式对增长曲线模型系数矩阵B的极大似然估计的局部影响分析 。

Generalized influence function and generalized Cook distance are used to study local influence of observations on the parameter estimation in the growth cruve model with an unknown Rao's simple covariance structure. The diagnostics under the perturbations of error variance, response variables and design variables are derived. An example are analyzed for illustration.
