参考Wiki上关于财富基尼系数计算公式的定义: In some cases, this equation can be applied to calculate the Gini coefficient without direct reference to the Lorenz curve. For example, (taking y to mean the income or wealth of a person or household): For a population uniform on the values yi, i...
Gini’s coefficient defined under the formalism of a fraud-scoring framework given in Equation 9 is equivalent to the expression derived for the revenue inequality in Equation 2, under the assumption that the credit score variable stands in place of the revenue variable. Proof From Equation 3 it...

Measuring inequality: the Gini Index1Math 128 – Fall 2005Introduction Most people would agree that “good things,” such as money income, should b..
The most frequently used index of inequality is perhaps the Gini coefficient attributed to Gini(1912) and analysed, among others, by Dalton(1920), Atkinson(1970), Newbery (1970), Kats(1972), Sheshinski(1972), Dasgupta, Sen and Starrett(1973), Rothschild and Stiglitz(1973), Sen(1973, 1974...
Three-way classifications Rough sets Impurity Gini coefficient Objective function 1. Introduction Three-way decisions are formed based on the notions of acceptance, rejection and non-commitment [34]. Three-way classification is one of main formulations of three-way decisions [35]. Given U a finite...
