Estimating Lorenz and Concentration Curves [PDF]
The Stata Journal: Promoting communications on statistics and Stata, 2016 Lorenz and concentration curves are widely used tools in inequality research. In this article, I present a new command, lorenz, that estimates Lorenz and concentration curves from individual-level data and, optionally, displays the results in a graph.

Application of Lorenz-curve model to stratified water injection evaluation
Petroleum Exploration and Development, 2015 To evaluate the effect of stratified water injection accurately during different development stages, a Lorenz-curve model was constructed upon a modified four-parameter Sarabia-Lorenz-curve model with water injectivity test data over years, and the ...

Quantum relative Lorenz curves [PDF]
Physical 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 ...

Atmosphere, 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 Curve-Based Entropy Thresholding on Circular Histogram
IEEE Access, 2020 Circular histogram thresholding is a new threshold selection method in color image segmentation. However, the method of the existing circular histogram thresholding based on the Otsu Criteria lacks the generality of using the circular histogram. In order

Income inequality measures and the middle class [PDF]
SHS Web of Conferences, 2021 We study how the presence of the middle class in the sense of Gevorgyan-Malykhin affects the value of income inequality measures including the Gini coefficient J and the Hoover index H.

Lorenz-generated bivariate Archimedean copulas
Dependence 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
Mathematics, 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
RUDN 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.

Resource 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.
