摘要
从统计决策理论角度考虑了正态均值置信区间的改进问题.利用未知分布参数之间的序限制,通过使用改进估计量的IERD方法,对无序限制情况下正态均值的minimax置信区间进行了改进,构造了一族改进置信区间.
This paper considers the improvement of the usual eonfidence interval for a normal mean from the decision theory point of view. By combining the IERD method of the parameter estimator which is used in the estimation theroy, with the order restriction of the unknown distribution parameters, the usual equivariant minimax confidence interval is improved and a class of improved confidence intervals are constructed.
