摘要
对生长曲线模型的最小二乘估计(LSE)与最佳线性无偏估计(BLUE)定义了一种新的相对效率,新的相对效率定义为最上特征根的比值,研究了它的下界,并讨论了它与已有的三种相对效率之间的关系.
A new relative efficiency is proposed for LSE and BLUE of the growth curve model.The relative efficiency is defined as the ratio between the least eigenvalues.Study is made about its lower bound.Finally a discussion is conducted on its relation with the other three existing relative efficiencies.
