Asymptotic Behaviors of the Lorenz Curve for Left Truncated and Dependent Data [PDF]

Journal of Sciences, Islamic Republic of Iran, 2012
The purpose of this paper is to provide some asymptotic results for nonparametric estimator of the Lorenz curve and Lorenz process for the case in which data are assumed to be strong mixing subject to random left truncation.

The Lorenz curve: a novel method for understanding viral load distribution at the population level. [PDF]

AIDS, 2017
Existing HIV care cascade metrics fail to capture whether viremia is equally distributed in a population or concentrated within groups. We applied the Lorenz curve, which has been used to describe disparities in the distribution of income and other ...

Lorenz Curve Interpolation and the Gini Coefficient

Journal of Income Distribution®, 2010
This article presents a simple non-polynomial spline that may be used to construct Lorenz curves from grouped data. The spline is naturally convex and works by determining a series of piecewise segments that may be joined to give a smooth and continuous Lorenz curve.

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 ...

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

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.

Carbon Lorenz curves [PDF]

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.
