D-vine copula based quantile regression and the simplifying assumption for vine copulas [PDF]

open access: yes, 2017
In the first part of this thesis we propose a novel semiparametric approach to perform quantile regression using D-vine copulas, a subclass of the flexible class of vine copula models. Various applications and the extension to discrete data are presented.

Contributions to Vine-Copula Modeling

open access: yes, 2022
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 of their marginaldistributions, which is deemed the most valued characteristic of these models.
