Study on Wind Field Characteristics in a Coastal Plain Based on a New Three-Dimensional Joint Distribution Model

open access: yesApplied Sciences, 2021
This paper studied the joint probability distribution of wind speed, wind direction, and wind height. The measured wind field data of a coastal plain in Zhongshan city, Guangdong Province, China, were taken as the research object.

Identification and Risk Characteristics of Agricultural Drought Disaster Events Based on the Copula Function in Northeast China

open access: yesAtmosphere, 2022
Accurate feature identification of drought disaster events is required for proper risk management in agriculture. This study improved the crop water deficit index (CWDI) by including the daily meteorological, crop development stage, soil moisture content,

New bivariate and multivariate log-normal distributions as models for insurance data

open access: yesResults in Applied Mathematics, 2022
The body of most multivariate financial data sets can be well modeled by log-normal distributions. Yet not many multivariate log-normal distributions are available in the literature.

Idealized models of the joint probability distribution of wind speeds [PDF]

open access: yesNonlinear Processes in Geophysics, 2018
The joint probability distribution of wind speeds at two separate locations in space or points in time completely characterizes the statistical dependence of these two quantities, providing more information than linear measures such as correlation. In

How to find a joint probability distribution of minimum entropy (almost) given the marginals [PDF]

open access: yesInternational Symposium on Information Theory, 2017
Given two discrete random variables X and Y, with probability distributions p = (p1, …, pn) and q = (q1, …, qm), respectively, denote by C(p, q) the set of all joint distributions of X and Y that have p and q as marginals.

Wind-ice Joint Probability Distribution Analysis based on Copula Function

open access: yesJournal of Physics: Conference Series, 2020
Taking the wind speed and ice thickness field measurement data in Southwest China during November 2016 to March 2018 as analytical sample, the probability distribution of the wind speed and ice intensity were analyzed and fitted by using Gumbel ...

Optimal Formula about Ordering the Random Variables Problem [PDF]

open access: yesEurasian Journal of Science and Engineering, 2018
In this paper, we propose an algorithm about ordering the random variables into order statistics and find the simple formula of multi order statistics joint probability distribution and endeavor to prove it mathematically.
