Bayesian approach to Lorenz curve using time series grouped data [PDF]
Journal of business & economic statistics, 2019 This study is concerned with estimating the inequality measures associated with the underlying hypothetical income distribution from the times series grouped data on the income proportions.

Re-Expression of the Lorenz Asymmetry Coefficient on the Rotated and Right-Shifted Lorenz Curve of Leaf Area Distributions [PDF]
PlantsThe Gini coefficient, while widely used to quantify inequality in biological size distributions, lacks the capacity to resolve directional asymmetry inherent in Lorenz curves, a critical limitation for understanding skewed resource allocation strategies.

Distribution of hospital beds in Tehran Province based on Gini coefficient and Lorenz curve from 2010 to 2012. [PDF]
Electron Physician, 2015 Introduction Fair distribution of hospital beds across various regions is a controversial subject. Resource allocation in health systems rarely has focused on those who need it most and, in addition, is often influenced by political interests.

Ranking Intersecting Lorenz Curves [PDF]
Social Choice and Welfare, 2004 This paper is concerned with the problem of ranking Lorenz curves in situations where the Lorenz curves intersect and no unambiguous ranking can be attained without introducing weaker ranking criteria than first-degree Lorenz dominance. To deal with such

Characterizing compressibility with Lorenz curves [PDF]
2011 IEEE International Symposium on Information Theory Proceedings, 2011 This paper revisits earlier work on rate distortion behavior of sparse sources, namely it highlights the fact that a graphical sparsity characterization proposed in [1] is a Lorenz curve, a tool for summarizing income inequality that has been used by economists for over a century. The Lorenz curve associated to a memoryless source can be used to obtain

Estimating the Empirical Lorenz Curve and Gini Coefficient in the Presence of Error [PDF]
, 2007 The Lorenz curve is a graphical tool that is widely used to characterize the concentration of a measure in a population, such as wealth. It is frequently the case that the measure of interest used to rank experimental units when estimating the empirical ...

Quantile versions of the Lorenz curve [PDF]
Electronic Journal of Statistics, 2015 The classical Lorenz curve is often used to depict inequality in a population of incomes, and the associated Gini coefficient is relied upon to make comparisons between different countries and other groups.

Decomposition of Lorenz Trajectories Based on Space Curve Tangent Vector
AtmosphereThis article explores the evolution of Lorenz trajectories within attractors. Specifically, based on the characteristics of the tangents to trajectories, we derive quantitative standards for determining the spatial position of trajectory lines.

Continuous L1 Norm Estimation of Lorenz Curve
Bangladesh Journal of Multidisciplinary Scientific Research, 2019 In this paper, the L1 norm of continuous functions and corresponding continuous estimation of regression parameters are defined. The continuous L1 norm estimation problem of one and two parameters linear models in the continuous case is solved.

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.
