摘要
运用枢轴量法,借助于χ~2分布,就一般连续型非正态总体情形,证明了一类能够派生出总体分布中未知参数之精确置信区间构造方法的定理,并举例说明其应用.
In this paper,applying the pivotal quantity method,by means of χ2distribution,the theorem that derives the construction method about the precise confidence interval of unknown parameter for general continuous non-normal population distribution is proved,and a numerical example is given to illustrate it＇s application.
