正态分布变差系数的置信区间

摘要

A problem of the estimation of the coefficient of variation for the normal distribution was discussed. A new pivotal variable to construct the classical confidence intervals for the coefficient of variation was given. And precision confidence intervals for the coefficient of variation of the normal distribution with a simple expression were also obtained.%研究正态分布的变差系数估计问题.提出了一个新的枢轴量来构造变差系数的经典置信区间,给出了正态分布变差系数的具有简单表达式的精确置信区间.
