摘　　要：对于含随机效应的生长曲线模型,当随机效应阵D和误差阵R为数乘单位矩阵时,利用向量化算法把模型转化为含两个方差分量的混合效应模型,利用谱分解法能够同时得到模型的固定效应和随机效应的谱分解估计,并给出了估计的性质.For growth curve models with random effects, when the random effects matrix D and a unit matrix multiple, the method of vectorization algorithm is applied to translate it into a model with two variance components. Using the application of spectral decomposition to obtain random effects spectral decomposition estimates at the same time, and are some natures of the the error matrix R is linear mixed effects the fixed effects and estimates.
