Comparing cross‐country estimates of Lorenz curves using a Dirichlet distribution across estimators and datasets
基于狄利克雷分布比较不同估计方法与数据集中的跨国洛伦兹曲线估计
Summary Chotikapanich and Griffiths ( Journal of Business and Economic Statistics , 2002, 20 (2), 290–295) introduced the Dirichlet distribution to the estimation of Lorenz curves. This distribution naturally accommodates the proportional nature of income share data and the dependence structure between the shares. Chotikapanich and Griffiths fit a family of five Lorenz curves to one year of Swedish and Brazilian income share data using unconstrained maximum likelihood and…
