| Abstract: | This paper firstly shows the relationship between a good point estimator and confidence intervals by analyzing the procedure of estimating the confidence intervals with pivotal quantities.According to Lehmann-Sheffe theorem,the sufficient statistics plays very important role in searching the proper pivotal quantities.It proposes an efficient method to estimate confidence intervals by constructing pivotal quantities with sufficient statistics. |
