误差方差阵奇异下推广的生长曲线模型中未知参数矩阵的BLU估计

The Parameter Estimate on the Singular Model of the Extensive Growth Curve

通过矩阵的拉直运算 ,将推广的生长曲线模型化为经典的线性模型的情形 .在误差方差阵V≥ 0的条件下 ,对未知参数矩阵得到了与著名统计学家Rao相类似的结果 ,为生物学中生长曲线模型在奇异情形下的研究奠定了理论基础 .

In this paper, the singular model of the extensive growth curve is converted into a classical linear model by the vectorizen calculation of matrix. The same result as that of the famous statist Rao can be obtained, which will lay a theoretic foundation for the model of the growth curve in biology.
