A family of elliptic Lorenz curves is proposed for fitting grouped income data. The associated distribution and density functions are displayed together with the Gini indices. Estimation procedures are discussed. Comparisons are made with alternative models using Australian 1967--68 income data.

Novel credibility approaches for Lorenz curve and Gini coefficient estimation
Statistics (Berlin)The Lorenz curve and Gini coefficient are prominent statistical tools used in various fields to measure income inequality, wealth distribution, and other distributions of resources within a population. However, traditional estimations of Lorenz curve and

Lorenz Densities and Lorenz Curves
2014Lorenz curves and Lorenz densities are introduced for real-valued random variables with finite and strictly positive expectation. Gastritic’s definition of a Lorenz curve is used. Basic properties of Lorenz curves are given as well as approximation results.

Use of the Lorenz curve to measure size inequality and growth dominance in forest populations
Australian Forestry, 2018Devised in 1905, the Lorenz curve was used initially to study inequality in income distribution in human populations. Its principles have been adapted to provide measures of the size inequality between individuals in plant populations and to assess the ...

Abstract This paper presents a functional form, linear in the parameters, to deal with income distribution and Lorenz curves. The function is fitted to the Brazilian income distribution. Data standard deviations were estimated from year-to-year variation of the income share.

Identification of the Lorenz curve by Lorenz coefficient
Weltwirtschaftliches Archiv, 1981Die Identifikation der Lorenzkurve durch Lorenzkoeffizienten. — Der aus der Lorenzkurve abgeleitete Gini-Koeffizient vermittelt einen guten Eindruck von dem Ma\ an Ungleichheit. WAhrend sich jedoch eine Lorenzkurve auf den Gini-Koeffizienten im VerhAltnis eins zu eins ubertragen lA\t, entspricht — in der entgegengesetzten Richtung — ein Gini ...

Lorenz curve of a light beam: evaluating beam quality from a majorization perspective.
Applied Optics, 2017We introduce a novel approach for the characterization of the quality of a laser beam that is not based on particular criteria for beam width definition.

We study the Generalized Lorenz curves of the minima of samples from a random variable. These Lorenz curves can be used to compare distributions in terms of their variability and define coherent risk measures. The dual Lorenz curves of the maxima of samples from the random variable are also considered.
