The Gini Index of Speech
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. The Gini index, introduced in 1912, is one of the most common measures of i...
متن کاملThe Gini Index and Measures of Inequality
The Gini index is a summary statistic that measures how equitably a resource is distributed in a population; income is a primary example. In addition to a self-contained presentation of the Gini index, we give two equivalent ways to interpret this summary statistic: first in terms of the percentile level of the person who earns the average dollar, and second in terms of how the lower of two ran...
متن کاملMeasuring Healthcare Inequities using the Gini Index
Questions of healthcare inequities have been of continuing concern to health researchers, planners, and policymakers. The answers to such questions can be difficult to interpret, but deeply affect policy formulation, resource allocation, and our perceptions of the fairness and compassion inherent in the institutions of government and society as a whole. This paper describes the data warehouse i...
متن کاملReliable Inference for the Gini Index
Although attention has been given to obtaining reliable standard errors for the plugin estimator of the Gini index, all standard errors suggested until now are either complicated or quite unreliable. An approximation is derived for the estimator by which it is expressed as a sum of IID random variables. This approximation allows us to develop a reliable standard error that is simple to compute....
متن کاملAn elementary characterization of the Gini index
The Gini index is one of the most used indicators of social and economic inequality. In this paper we characterize the Gini index as the unique function that satis es the properties of scale independence, symmetry, standardization and separability. Furthermore, we propose a simpler way to compute it. Keywords: Gini index; income inequality; axiomatization. JEL Classi cation: D31, D63, I31. 1 In...
