The lognormal distribution is widely used to describe the distribution of positive random
variables; in particular, it is used to model data relevant to occupational hygiene and to …

In this paper we conduct a simulation study to evaluate coverage error, interval width and
relative bias of four main methods for the construction of confidence intervals of log‐normal …

Boostrap procedures for computing lower and upper confidence limits for the mean of a log-
normal distribution based on complete samples are presented. The procedures are based …

On June 13/14, 1998, a first simultaneous five‐color lidar measurement of a noctilucent
cloud was realized. The experiment was made possible by the fact that at the site of our …

In the era of sustainable agriculture, the issue of proper and precise implementation of
agrotechnical operations, without harmful effects on the natural environment, begins to play …

We focus on the construction of confidence intervals for the ratios of medians of two
independent, log-normal distributions based on the normal approximation (NA) approach …

Approximate and generalized confidence bands for some parametric functions of the
univariate lognormal diffusion process with exogenous factors are obtained. The procedures …

Data analysts often compute approximate 100 (1‐α) per cent confidence intervals for the
mean of a log‐normal random variable due to the computational effort required for exact …

We consider selection problems on k lognormal (/spl mu//sub i/,/spl sigma//sub i//sup 2/)
populations when the/spl sigma//sub i//sup 2/are unequal, under both known & unknown …

We focus on the normal approximation for point estimation of the ratios of medians of two
independent, log-normal distributions. We investigate its performance in terms of bias …
