A normal relationship ? Poverty, growth, and inequality [PDF]

Using a large cross-country income distribution dataset spanning close to 800 country-year observations from industrial and developing countries, the authors show that the size distribution of per capita income is well approximated empirically by a ...

More adequate probability distributions to represent the saturated soil hydraulic conductivity

Scientia Agricola, 2002
The saturated soil hydraulic conductivity (Ksat) is one of the most relevant variables in studies of water and solute movement in the soil. Its determination in the laboratory and in the field yields high dispersion results, which could be an indication ...

Modelling NO2 emissions at Eskom’s Lethabo coal fired power station

Discover Environment
This study uses three relatively heavy tailed statistical distributions commonly applied in air pollution, namely, the Weibull, Lognormal and Pareto distributions, to characterise the NO2 emissions data (tons) from Lethabo coal fired power station, owned

The Partial Distribution: Definition, Properties and Applications in Economy [PDF]

In this discussed draft, we want to present the Partial Distribution (F.Dai, 2001) for discussing. We compare the partial distribution with lognormal and levy distribution.

Testing Special Cases of the GB2 Distribution: Comment and an Extension

We extend earlier work (Griffiths and Hill, 2025) by pointing out that a score test developed by Prentice (1975) for testing whether a normal distribution is an adequate representation of the log of a GB2 random variable is suitable for testing whether a

Análisis bayesiano para la distribución lognormal generalizada aplicada a modelos de falla con censura Bayesian Analysis for the Generalized Lognormal Distribution Applied to Failure Time Analysis

Revista Colombiana de Estadística, 2011
Existen varias versiones de la distribución lognormal en la literatura estadística y una de ellas está basada en la transformación exponencial de la distribución normal generalizada (NG).

Common Correlation and Calibrating the Lognormal Forward Rate Model [PDF]

1997 three papers that introduced very similar lognormal diffusion processes for interest rates appeared virtuously simultaneously. These models, now commonly called the 'LIBOR models' are based on either lognormal diffusions of forward rates as in Brace,

BAYESIAN ANALYSIS FOR THE GENERALIZED LOGNORMAL DISTRIBUTION APPLIED TO FAILURE TIME ANALYSIS ANÁLISIS BAYESIANO PARA LA DISTRIBUCIÓN LOGNORMAL GENERALIZADA APLICADA A MODELOS DE FALLA CON CENSURA

Revista Colombiana de Estadística, 2011
There are several versions of the lognormal distribution in the statistical literature, one is based in the exponential transformation of generalized normal distribution (GN).

LOGNFIT: Stata module to fit lognormal distribution by maximum likelihood

lognfit fits by ML the 2 parameter lognormal distribution to sample observations on a random variable. lognpred calculates statistics summarizing a lognormal distribution which has been fitted using lognfit.

QLOGNORM: Stata module for diagnostic plots for lognormal distribution

qlognorm plots the quantiles of varname against the quantiles of the corresponding lognormal distribution. plognorm graphs a standardized lognormal probability plot for varname.
