A vine copula mixed effect model for trivariate meta-analysis of diagnostic test accuracy studies accounting for disease prevalence [PDF]

open access: yes, 2015
A bivariate copula mixed model has been recently proposed to synthesize diagnostic test accuracy studies and it has been shown that it is superior to the standard generalized linear mixed model in this context.

Pair-copula constructions of multiple dependence [PDF]

open access: yes, 2006
Building on the work of Bedford, Cooke and Joe, we show how multivariate data, which exhibit complex patterns of dependence in the tails, can be modelled using a cascade of pair-copulae, acting on two variables at a time.

Research on the reliability allocation calculation method of a wind turbine generator set based on a vine copula correlation model

open access: yesEnergy Science & Engineering, 2021
To consider the failure correlation among key subsystems, based on the reliability allocation method of the series system, a wind turbine reliability allocation calculation method based on the vine copula correlation model is proposed.

Estimation of Extreme Quantiles for Functions of Dependent Random Variables [PDF]

open access: yes, 2013
We propose a new method for estimating the extreme quantiles for a function of several dependent random variables. In contrast to the conventional approach based on extreme value theory, we do not impose the condition that the tail of the underlying ...

A New Wind Speed Scenario Generation Method Based on Principal Component and R-Vine Copula Theories

open access: yesEnergies, 2022
The intermittent and uncertain properties of wind power have presented enormous obstacles to the planning and steady operation of power systems. In this context, as an effective technique to study wind power uncertainty, the development of an accurate ...
