| Abstract: | At first,the convergence performance in variance components estimation studied in the aspect of quality.The study indicated that the convergence performance is in related to the oscillating character of estimation equation of variance components.And then based on this study the author proposed a method to improve the convergence performance,and finally numerical examples were used to prove the validity of the method. |
