Proof of Equivalence of Three Methods for Estimation of Gini Coefficient

摘要: 用梯形法、矩形法、基尼计算法详细推导了基尼系数,并证明了在人口等分的条件下,这3种方法的等价性.

Abstract: Gini coefficient was detailed with trapezoidal method,rectangular method and Gini calculation.It was proved that the trapezoidal method,rectangular method and Gini calculation can be equivalent under the condition of equal division of population.
