摘要  在统计决策理论框架内考虑了Stein损失下的统计预测问题.利用估计问题中对无序限制下参数估计量的改进方法,结合未知分布参数之间的序限制,对通常的最优同变预测量进行了改进,构造了一族改进预测量,从而解决了Stein损失下最优同变预测量的改进问题,并给出了相应的例子. <Abstrcat>This paper considers statistical prediction problem from decision theoretic point of view.By combining the improving method of the parameter estimator,which is used in the estimation theory,with the order restriction of the unknown distribution parameters,the best equivariant predictor is improved and a class of improved predictors are constructed.A example is given.
