Bayesian Approach to Lorenz Curve Using Time Series Grouped Data
基于时间序列分组数据的洛伦兹曲线贝叶斯估计
This study is concerned with estimating the inequality measures associated with the underlying hypothetical income distribution from the times series grouped data on the income proportions. We adopt the Dirichlet likelihood approach where the parameters of the Dirichlet likelihood are set to the differences between the Lorenz curve of the hypothetical income distribution for the consecutive income classes and propose a state-space model which combines the transformed…
