Log-Normal Distribution of Tablet Pore Diameters

Journal of Pharmaceutical Sciences, 1974
The use of the log-normal distribution applied to the pore characteristics of tablets is discussed. An analytical method for the determination of the geometric mean pore diameter is presented and applied to several tablet samples. The method eliminates the necessity of plotting the pore volume data, eliminates subjective evaluation, and is amenable to ...

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 ...

Bayesian and Non-Bayesian Analysis of the Log-Normal Distribution and Log-Normal Regression

Journal of the American Statistical Association, 1971
Abstract In this article, Bayesian and non-Bayesian methods for estimating parameters of the log-normal distribution and of log-normal regression processes are considered. Posterior distributions for parameters of interest are derived and their properties are described. With respect to point estimation, a rather broad class of estimators is defined and,

On the log-normal distribution of electromigration lifetimes

Journal of Applied Physics, 1979
It has been shown that a normal temperature distribution within a sample set can produce a log-normal failure rate in electromigration experiments if it is assumed that the equation tf=Aj−n exp(Ef/kT) holds for individual stripe lifetimes. It has also been pointed out that if σ’s determined under accelerated-stress conditions are used to predict ...

Estimators of Log-Normal Distribution Parameters

IEEE Transactions on Aerospace and Electronic Systems, 1977
The maximum likelihood estimates of the median m and mean-to-median ratio ? for a log-normally distributed variate are derived, together with the asymptotic variances of these estimates. Using a Monte Carlo simulation, it is shown that these asymptotic variances of the estimates are reasonable when the number of sample points is N ? 50forp ? 8.

Normal or Log-normal: Appropriate Distributions

Nature, 1967
I WISH to point out that for the statistical analysis of certain types of data the assumption that the data are drawn from a normal population is usually wrong, and that the alternative assumption of a log-normal distribution is better. This alternative is widely used by statisticians, economists and physicists, but for some reason is often ignored by ...
