An Atkinson-Gini Family of Social Evaluation Functions [PDF]
We propose a class of social evaluation functions and of inequality indices which merge the useful features of the family of Atkinson (1970) and of S-Gini (Donaldson and Weymark (1980, 1983), Yitzhaki (1983) and Kakwani (1980)) indices.

Beta Forecasting With Realized Beta Estimators and Machine Learning Algorithms
Journal of Forecasting, EarlyView.ABSTRACT This paper applies machine learning algorithms to the modeling of realized betas for the purposes of forecasting stock systematic risk. Higher levels of beta forecast accuracy are demonstrated, relative to other studies in the literature. These improvements are also highly significant, both statistically and economically.

Comparison of the Gini and Zenga Indexes using Some Theoretical Income Distributions Abstract
Operations Research and Decisions, 2013 The most common measure of inequality used in scientific research is the Gini index. In 2007, Zenga proposed a new index of inequality that has all the appropriate properties of an measure of equality.

On Calculation of the Extended Gini Coefficient. [PDF]
The conventional formula for estimating the extended Gini coefficient is a covariance formula provided by Lerman and Yitzhaki (1989). We suggest an alternative estimator obtained by approximating the Lorenz curve by a series of linear segments.

The Gini index of speech [PDF]
, 2004 In which representation is speech most sparse? Time-scale? Time-frequency? Which window generator and length should be used to create the sparsest decomposition? To answer these questions, we propose the Gini index, which is twice the area between the Lorenz curve and the 45 degree line, as a measure of signal sparsity.

Health Care Science, EarlyView.The T cell‐inflamed gene expression profile (GEP) provides a biomarker for immunotherapy response across various cancers. We established a CT‐based radiomics model to predict the T cell‐inflamed GEP and immunotherapy response in hepatocellular carcinoma (HCC).

Decomposition of Gini and the generalized entropy inequality measures [PDF]
In this article we provide an overview of the Gini decomposition and the generalized entropy inequality measures, a free access to their computation, an application on French wages, and a different way than Dagum to demonstrate that the Gini index is a ...
