Lognormal Lorenz and normal receiver operating characteristic curves as mirror images [PDF]

open access: yesRoyal Society Open Science, 2015
The Lorenz curve for assessing economic inequality depicts the relation between two cumulative distribution functions (CDFs), one for the distribution of incomes or wealth and the other for their first-moment distribution.

Modified Lorenz Curve and Its Computation

open access: yesDesimal, 2020
The Lorenz curve is generally used to find out the inequality of income distribution. Mathematically a standard form of the Lorenz curve can be modified with the aim of simplicity of its symmetric analysis and calculation of the Gini coefficient that ...

Quantifying the Economic Development Dynamics of a Country Based on the Lorenz Curve

open access: yesE+M Ekonomie a Management, 2021
The welfare of a country depends on its economic development. In order to have the impact on it, we should have a possibility to quantitatively assess its situation at the desired point in time.

Quantum relative Lorenz curves [PDF]

open access: yesPhysical Review A, 2017
The theory of majorization and its variants, including thermomajorization, have been found to play a central role in the formulation of many physical resource theories, ranging from entanglement theory to quantum thermodynamics. Here we formulate the framework of quantum relative Lorenz curves, and show how it is able to unify majorization ...

Evaluation of an Alternative Functional Form to Fit the Lorenz Curve for the Concentration Index Calculation

open access: yesAtmosphere, 2023
Precipitation concentration indices have become a popular tool for analyzing the structure of daily precipitation amounts. Among the existing indices, the concentration index (CI) is widely used.

Lorenz-generated bivariate Archimedean copulas

open access: yesDependence Modeling, 2020
A novel generating mechanism for non-strict bivariate Archimedean copulas via the Lorenz curve of a non-negative random variable is proposed. Lorenz curves have been extensively studied in economics and statistics to characterize wealth inequality and ...

Asymptotic Results in Broken Stick Models: The Approach via Lorenz Curves

open access: yesMathematics, 2020
A stick of length 1 is broken at random into n smaller sticks. How much inequality does this procedure produce? What happens if, instead of breaking a stick, we break a square? What happens asymptotically?

Group averaging and the Gini deviation

open access: yesRUDN Journal of Economics, 2021
It is known that partitioning a society into groups with subsequent averaging in each group decreases the Gini coefficient. The resulting Lorenz function is piecewise linear.

Assessing spatial inequality in cancer service access in regional areas

open access: yesCogent Public Health, 2022
This paper applies economic concepts from measuring income inequality to an exercise in assessing spatial inequality in cancer service access in regional areas. We propose a mathematical model for accessing chemotherapy among local government areas (LGAs)

Carbon Lorenz curves [PDF]

open access: yesResource and Energy Economics, 2010
The purpose of this paper is twofold. First, it exhibits that standard tools in themeasurement of income inequality, such as the Lorenz curve and the Gini-index,can successfully be applied to the issues of inequality measurement of carbonemissions and the equity of abatement policies across countries.
