Generating Networks to Target Assortativity via Archimedean Copula Graphons
Victory Idowu
We develop an approach to generate random graphs to a target level of assortativity by using copula structures in graphons. Unlike existing random graph generators, we do not use r…

On tail dependence parameters for non-continuous and autocorrelated margins
Victory Idowu
Tail dependence plays an essential role in the characterization of joint extreme events in multivariate data. However, most standard tail dependence parameters assume continuous ma…

A Topological Proof of the Archimedean Axiom for Archimedean Copulas
Victory Idowu
Archimedean copulas are a popular type of copulas in which a variant of the Archimedean axiom apply. We provide a topological proof of the Archimedean Axiom which is applicable for…
