Estimating Lorenz Curves Using a Dirichlet Distribution. [PDF]
The Lorenz curve relates the cumulative proportion of income to the cumulative proportion of population. When a particular functional form of the Lorenz curve is specified it is typically estimated by linear or nonlinear least squares, estimation ...

Assessing Economic Inequality Through the Lorenz Curve in Central and Eastern European Countries [PDF]
Ovidius University Annals: Economic Sciences SeriesThis study analyses economic inequality in Central and Eastern Europe (CEE) using tools such as the Lorenz Curve and the Gini coefficient. Originating in 1905, the Lorenz Curve, conceptualized by Max O.

Mucosa‐Interfacing Capsule for In Situ Sensing the Elasticity of Biological Tissues
Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.A fundamental mechanism of palpating soft materials is reported to sense deep tissue elasticity in situ with minimal invasion using the interaction between the robot palpation unit and soft tissues. Both the robot locomotion and elasticity sensing functions are remotely controlled by external magnetic fields, while the sensing data are wirelessly ...

Concepts of Reliability Theory and Their Relationship with the Economic Inequality indicators
پژوهشهای ریاضی, 2020 Introduction One of the intersecting aspects of the reliability theory and economics is investigating non-negative data generally skewed (lifetimes and income), extrapolation of a suitable model for the data and finding their characteristics ...

On a property of Lorenz curves with monotone elasticity and its application to the study of inequality by using tax data [PDF]
, 2017 The Lorenz curve is the most widely used graphical tool for describing and comparing inequality of income distributions. In this paper, we show that the elasticity of this curve is an indicator of the effect, in terms of inequality, of a truncation of ...
