摘要/Abstract

摘要： 考虑有限制位置参数下随机变量的统计预测问题. 利用可得到的相关数据及参数间的两种不同序限制, 对随机变量的单收缩预测量进行改进, 得到了不同序限制下的改进预测量族, 并探讨了改进预测量族之间的关系.

Abstract: This paper devotes to a statistical prediction problem under restricted location parameters. The improvement of the single-shrinkage predictor of the random variable was made by means of all the available data and two kinds of different parameter restrictions. The relation of improved predictors sets with different parameter restriction is dis cussed.

Key words: statistical prediction, restricted location parameters, singleshrinkage predictor, improved predictor
