摘要
洛伦兹曲线的准确度关系到基尼系数的精度,结合2006年湖北省农村和城镇的收入分组数据,分别针对性地提出一个洛伦兹曲线新模型。通过对2种新模型的初次分析,从拟合度上可以表明拟合效果很好。新模型拟合效果从全部模型来看还是相当好的。
Accuracy of Gini Coefficient is closely related to the accuracy of the lorenz curve, combined with 2006 reve-nue of Hubei rural and urban packet data, a new model of lorenz curve was respectively proposed. Through the analy-sis of the two new models, from the fitting degree, it could be shown that the fitting effect was very good. comparativeresults showed that new model fitting effect among all models was still quite good.
