# A Convenient Method of Decomposing the Gini Index by Population Subgroups

@inproceedings{Ogwang2014ACM, title={A Convenient Method of Decomposing the Gini Index by Population Subgroups}, author={Tomson Ogwang}, year={2014} }

Abstract We propose a convenient method of estimating the within-group, between-group, and interaction components of the overall traditional Gini index from the estimated parameters of underlying “trick regression models” involving known forms of heteroscedasticity related to income. Two illustrative examples involving both real and artificial data are provided. The issue of appropriate standard error of the subgroup decomposition is also discussed.
