吉尼系数的计算及正态分布的吉尼系数

Calculation of Gini Efficient and Gini Efficient of Distribution

本文给出了吉尼系数的一般计算公式 ,推导出正态分布的吉尼系数渐进无偏估计 ,并以实例对比了传统的吉尼系数的算法——万分法与本文中提出的估计方法。

A general calculation equation for Gini coefficient was present, the asymptortically unbiasses estimation of Gini coefficient of general distribution was deduced, and a case was used make a comparison between the one/ten thousand method, the traditional method for Gini coefficient calculation and the new method.
