摘要
首先给出了含随机效应增长曲线模型中回归参数阵两步估计的一个较为简单的计算方法;然后给出了回归参数阵的可估函数的两步估计具有无偏性的一个基本结论,并证明了两种常见两步估计均具有无偏性;最后给出了一个牙齿生长数据的实例模拟.
Firstly, a simple computing method is given for the two-stage estimate of regression coefficient matrix in the Growth Curve Model with Random Effects. Then the unbiased property of the two-stage estimate was become an unbiased estimate is proved. Finally, an example of dental growth data is given.
