Description of the Joint Probability of Significant Wave Height and Mean Wave Period

open access: yesJournal of Marine Science and Engineering, 2022
The bivariate probability distribution of significant wave heights and mean wave periods has an indispensable guiding role in the implementation of offshore engineering, which has attracted great attention.

Human behavior and lognormal distribution. A kinetic description [PDF]

open access: yesMathematical Models and Methods in Applied Sciences, 2018
In recent years, it has been increasing evidence that lognormal distributions are widespread in physical and biological sciences, as well as in various phenomena of economics and social sciences.

Corrected Maximum Likelihood Estimations of the Lognormal Distribution Parameters

open access: yesSymmetry, 2020
As a result of asymmetry in practical problems, the Lognormal distribution is more suitable for data modeling in biological and economic fields than the normal distribution, while biases of maximum likelihood estimators are regular of the order O ( n − 1

Novel approach to predicting the release probability when applying the MARSSIM statistical test to a survey unit with a specific residual radioactivity distribution based on Monte Carlo simulation

open access: yesNuclear Engineering and Technology, 2022
For investigating whether the MARSSIM nonparametric test has sufficient statistical power when a site has a specific contamination distribution before conducting a final status survey (FSS), a novel approach was proposed to predict the release ...

Estimation of the Lognormal Distribution Function [PDF]

open access: yesThe Egyptian Statistical Journal, 1976
Minimum variance unbiased estimates of the lognormal distribution with parameters µ and σ² are given for all possible cases: when σ² is known, when µ is known and when both µ and σ² are unknown.

A Left and Right Truncated Lognormal Distribution for the Stars [PDF]

open access: yes, 2017
The initial mass function for the stars is often modeled by a lognormal distribution. This paper is devoted to demonstrating the advantage of introducing a left and right truncated lognormal probability density function, which is characterized by four ...

On a Property of the Lognormal Distribution [PDF]

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1963
SUMMARY In this paper it is established that the lognormal distribution is not determined by its moments. Some brief comments are made on the set of distributions having the same moments as a lognormal distribution.

Skewed distribution of spines is independent of presynaptic transmitter release and synaptic plasticity, and emerges early during adult neurogenesis

open access: yesOpen Biology, 2023
Dendritic spines are crucial for excitatory synaptic transmission as the size of a spine head correlates with the strength of its synapse. The distribution of spine head sizes follows a lognormal-like distribution with more small spines than large ones ...
