Bayesian estimation of Lorenz curve, Gini-index and variance of logarithms in a Pareto distribution
Statistica, 2007 In this article, we estimate Lorenz curve, Gini-index and variance of logarithms for Pareto distribution using Bayesian framework with a conjugate prior.

Growth and Inequality in Ireland, 1987 - 1999 [PDF]
This paper analyses data from the Irish Household Budget Surveys of 1987, 1994 and 1999 to examine the evolution of inequality of income and expenditure over that period.

, 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 resources, to the distribution of viremia in a safety-net HIV clinic in 2012.

physica status solidi (RRL) – Rapid Research Letters, EarlyView.Energetic particles make space a harsh environment that solar cells must endure. This study demonstrates that proton flux critically affects radiation damage in Cu(In,Ga)Se2 solar cells. By irradiating identical cells at different fluxes, a flux‐dependent balance between defect generation and dynamic annealing was revealed.

Pareto law of the expenditure of a person in convenience stores
, 2007 We study the statistical laws of the expenditure of a person in convenience stores by analysing around 100 million receipts. The density function of expenditure exhibits a fat tail that follows a power law.

When tiny convective spread affects a midlatitude jet: Spread sequence
Quarterly Journal of the Royal Meteorological Society, EarlyView.We investigate spread evolution by mesoscale convection from tiny initial condition uncertainty during a real event. There is significant variation among the systems in their propensity to interact with the jet stream, whereby variability in one system (due to convective and long‐wave radiative heating tendencies) tightly relates to Rossby‐like ...

TWO NEW EXPONENTIAL FAMILIES OF LORENZ CURVES [PDF]
We present two new Lorenz curve families by using the basic model proposed by Sarabia, Castillo and Slottje (1999). We present estimations which show that the models in our new families are very efficient when applied to data on income distribution for a

Data assimilation with extremum Monte Carlo methods
Quarterly Journal of the Royal Meteorological Society, EarlyView.This study presents the extremum Monte Carlo filter as a data assimilation method and, in particular, a variant of the variational approach (three‐ and four‐dimensional variational), where the state estimates are obtained by solving an optimization problem numerically over a space of prediction functions, instead of the state space itself.

The Lorenz curve in economics and econometrics [PDF]
This paper surveys selected applications of the Lorenz curve and related stochastic orders in economics and econometrics, with a bias towards problems in statistical distribution theory. These include characterizations of income distributions in terms of

Quarterly Journal of the Royal Meteorological Society, EarlyView.The predictability of western and eastern North Pacific blocking events is assessed using analogue‐based diagnostics. Eastern blocks exhibit lower predictability, characterized by faster error growth and higher mean logarithmic divergence rates. The study highlights geographical contrasts in blocking stability.
