变差系数及其在概率分布特性分析中的应用

Coefficient of Variation and its Application to Characteristic Analysis of Statistical Distributions

阐述了交差系数在概率分布特性分析中的应用．通过建立交差系数与统计参数之间的简化关系，我们可以用变差系数来分析概率分布的形状和特性，并用实例说明了变差系数在统计参数近似计算中的简洁性．

Deals with an application of coefficient of variation to characteristic analysis of statistical distribution.By finding out the simplified relation between coefficient of variation and statistical parameter,we can analyse the appearance and the characteristic of statistical distribution with coefficient of variation. we also describe the facility of coefficient of variation in the approximate calculation of statistical parameter with an example.
