权因子法方差分量估计

The Method of Weight Factor for Variance Component Estimation

  • 摘要: 文中阐述了权因子法方差分量估计的原理。利用权因子的概念,对目前方差分量估计存在的几个问题,如负方差问题,作了探讨,并与Helmert法进行比较,得出了一些有益的看法。算例很好地说明了权因子法方差分量估计的简便和实用性。

     

    Abstract: This paper gives the method of Weight Factor(WF) for variance component estima-tion. According to Weight Factor, some questions, for example, negatiye variance are dis-cussed. And comparing the method of WF with that of Helmert, some valuable ideashave been got. Given examples show the method is simple and feasible.
