The multivariate Poisson-log normal distribution

Biometrika, 1989
For the statistical analysis of multivariate counts, as they may arise in ecology as the numbers of different species in geographical areas, a rich parametric class of multivariate count distributions would be useful. After a review of the corresponding literature the paper gives a study of the multivariate Poisson-log normal class of distributions ...

The beta log-normal distribution

Journal of Statistical Computation and Simulation, 2013
For the first time, we introduce the beta log-normal (LN) distribution for which the LN distribution is a special case. Various properties of the new distribution are discussed. Expansions for the cumulative distribution and density functions that do not involve complicated functions are derived.

Hearing Impairment and the Log-Normal Distribution

Applied Statistics, 1996
SUMMARY Data on hearing impairment are studied by using a three-parameter log-normal distribution, all of whose parameters depend on covariates. The fitting algorithm is an extension of generalized linear modelling. Questions for research include the estimation of a base-line distribution of hearing threshold levels for an 'unexposed' population and ...

Precipitator efficiency for log-normal distributions

Atmospheric Environment (1967), 1982
Abstract The work of Allander and Matts with its subsequent continuation by Matts and Ohnfeldt, on the efficiency of electrostatic precipitation for polydispersed particles, has attracted a certain amount of interest in recent years because of its actual and potential usefulness.

Log-normal distributions in parasitology

Proceedings: Animal Sciences, 1984
A uniform log-normal pattern of frequency distribution of cestodes and nematodes in poikilothermic and homeothermic hosts from Garhwal Himalayan ecosystems by size and weight classes during infection period indicates subtle relationship to the range of variation in the earth’s environment.

The log-normal distribution function

Journal of Chemical Education, 1972
The log-normal distribution function is a useful function that could be profitably introduced to the undergraduate and used more frequently in chemical research because of its relatively simple analytical form and the diverse physical mechanisms and models that can generate it.

Dissolution Rate Patterns of Log‐Normally Distributed Powders

Journal of Pharmaceutical Sciences, 1972
Particles dissolving in a dissolution medium initially decrease in linear dimension, while the number of particles remains unaltered. At a particular point in time (tc) the smallest particle disappears, and from that point on the number of particles decreases. These phenomena were simulated on a digital computer, and the agglomerate dissolution pattern
