摘要
研究了奇异增长曲线模型中均值矩阵的最小二乘估计的效率问题,给出了均值矩阵的最小二乘估计相对于最佳线性无偏估计的偏差估计,定义了均值矩阵的最小二乘估计相对于最佳线性无偏估计的相对效率,并给出了它们的上界.
In this paper we study the problem of model. We derive the estimatio of the mean matrix. Meanwhile n of the deviation efficiency about unknow mean between the Least squares and matrix in singular growth curve the Best linear unbias estimation a relative efficiency of LSE is proposed and its upper bound is given.
