Copula Modeling of COVID-19 Excess Mortality

open access: yesRisks
COVID-19’s effects on mortality are hard to quantify. Issues with attribution can cause problems with resulting conclusions. Analyzing excess mortality addresses this concern and allows for the analysis of broader effects of the pandemic.

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.

Learning Vine Copula Models for Synthetic Data Generation

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2019
A vine copula model is a flexible high-dimensional dependence model which uses only bivariate building blocks. However, the number of possible configurations of a vine copula grows exponentially as the number of variables increases, making model selection a major challenge in development.
