The Lognormal Distribution Is Characterized by Its Integer Moments
The lognormal moment sequence is considered. Using the fractional moments technique, it is first proved that the lognormal has the largest differential entropy among the infinite positively supported probability densities with the same lognormal-moments.

Inference with the lognormal distribution [PDF]
Several estimators of the expectation, median and mode of the lognormal distribution are derived. They aim to be approximately unbiased, efficient, or have a minimax property in the class of estimators we introduce.

Comparison of lognormal population means [PDF]
Comparisons of two lognormal population means are investigated. For large samples, the conventional test for significance of the population means is the ordinary Student t -test with normal critical value. By Chen and Loh’s result (Ann. Statist.

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,

Inference for double Pareto lognormal queues with applications [PDF]
In this article we describe a method for carrying out Bayesian inference for the double Pareto lognormal (dPlN) distribution which has recently been proposed as a model for heavy-tailed phenomena. We apply our approach to inference for the dPlN/M/1 and M/

Flexible lognormal sum approximation method
A simple and novel method is presented to approximate the distribution of the sum of independent, but not necessarily identical, lognormal random variables, by the lognormal distribution.

The transient data of the pinch force produced between the human forefinger and thumb have been shown to fit the functional form of the well-known lognormal density function.
