Contingency tables with structural zeros and discrete copulas

In this work, we analyze the connection between contingency table analysis and copulas in a discrete framework. We focus on the impact of structural zeros on the general theory presented by Geenens (2020) based on a new idea of copula models for discrete variables. Through examples, we investigate the pros and cons of applying the theory developed by Geenens (2020) and discuss some open questions for future research.
