Contributions to Vine-Copula Modeling [PDF]

open access: yes, 2022
144 p.Regular vine-copula models (R-vines) are a powerful statistical tool for modeling thedependence structure of multivariate distribution functions. In particular, they allow modelingdierent types of dependencies among random variables independently ...

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.

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 ...

Vine copula based dependence modeling in sustainable finance

open access: yesJournal of Finance and Data Science, 2022
Climate change and sustainability have become societal focal points in the last decade. Consequently, companies have been increasingly characterized by non-financial information, such as environmental, social, and governance (ESG) scores, based on which ...

Time series with infinite-order partial copula dependence

open access: yesDependence Modeling, 2022
Stationary and ergodic time series can be constructed using an s-vine decomposition based on sets of bivariate copula functions. The extension of such processes to infinite copula sequences is considered and shown to yield a rich class of models that ...

Development of decomposition-based model using Copula-GARCH approach to simulate instantaneous peak discharge

open access: yesApplied Water Science, 2023
Estimation of instantaneous peak discharge is important in the design of hydraulic structures and reservoir management. In this study, a new approach called CEEMD-Copula-GARCH is presented for simulating instantaneous peak discharge in the Qale Shahrokh ...

Factor Copula through a vine structure

open access: yes, 2015
Copula functions have been widely used in actuarial science, finance and econometrics. Though multivariate copulas allow for a flexible specification of the dependence structure of economic variables, they are not particularly tempting in high ...
