Consistent Nonparametric Tests for Lorenz Dominance [PDF]
This paper proposes a test for Lorenz dominance. Given independent samples of income or other welfare related variable, we propose a test of the null hypothesis that the Lorenz curve for one population is dominated by the Lorenz curve for a second ...

Population inequality: the case of repeat [PDF]
, 2005 This paper employs data from the 2000 British Crime Survey for England and Wales to discuss ways of illustrating the degree of inequality in the distribution of crime victimisation. In particular, Lorenz curves are presented for major crime categories, i.

Individualised niches: an integrative conceptual framework across behaviour, ecology, and evolution
Biological Reviews, EarlyView.ABSTRACT Individuals differ. While seemingly trivial, this insight has nevertheless led to paradigm shifts, as three key fields of organismal biology have seen marked changes in key concepts over the past few decades. In animal behaviour, it has become increasingly recognised that behavioural differences among individuals can be stable over time and ...

Application of the Gini coefficient for assessment of microbial communities` diversity in soil treated with biofertilizer [PDF]
Journal of Central European AgricultureMetabolic activity and structure of microbial communities are important indicators for soil health and fertility. BIOLOG`s Ecoplate patented technology provides a method for estimating soil microbial community structure based on different substrate ...

Parametric Lorenz Curves and the Modality of the Income Density Function [PDF]
, 2012 Similar looking Lorenz Curves can imply very different income density functions and potentially lead to wrong policy implications regarding inequality. This paper derives a relation between a Lorenz Curve and the modality of its underlying income density:

Measuring economic inequality and risk: a unifying approach based on personal gambles, societal preferences and references [PDF]
, 2015 The underlying idea behind the construction of indices of economic inequality is based on measuring deviations of various portions of low incomes from certain references or benchmarks, that could be point measures like population mean or median, or ...

ChemSusChem, Volume 18, Issue 6, March 15, 2025.The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

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 assuming that the ...

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 ...

ChemSusChem, Volume 18, Issue 6, March 15, 2025.Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...
