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.

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.

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?

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 ...

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

Recalculation of error growth models' parameters for the ECMWF forecast system [PDF]
Geoscientific Model Development, 2021 This article provides a new estimate of error growth models' parameters approximating predictability curves and their differentials, calculated from data of the ECMWF forecast system over the 1986 to 2011 period.

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.
