摘要
本文用投影理论及矩阵的谱分解方法 ,找出了推广的生长曲线模型的未知协方差矩阵Σ及tr(CΣ)在一定条件下的不变最小二乘无偏估计 ,为其估计的优良性的讨论奠定基础 .
The paper has figured out the invariant least square unbiased estimate of the unknown covariance Matrix Σ and tr(CΣ) on the extension of the Growth Curve Model,by means of the Projectiive Theory and the Pedigree decomposing of matrix,under certain circumstances on the designed matrices X i and W i,it has laid a foundation for the discussion on the excellence of the estimation.
