Getting nervous for the talk I'm about to give at a workshop about "using AI to drive impact" which features slides such as these.

I noticed that the convex functions that characterise f divergences can also be generators of Archimedean copulas. Here, I look at the case associated with the power divergences.
This seemingly 'simple' problem took me to some very strange places.

Power-divergence copulas: A new class of Archimedean copulas, with an insurance application
This paper demonstrates that, under a particular convention, the convex functions that characterise the phi divergences also generate Archimedean copulas in at least two dimensions. As a special case,...

Boris fighting off scurvy by eating a bit of mandarin. Don't worry; I took it off him after a few bites so as not to upset his little tummy (crop?).

Bayesian copula-based spatial random effects models for inference with complex spatial data
In this article, we develop fully Bayesian, copula-based, spatial-statistical models for large, noisy, incomplete, and non-Gaussian spatial data. Our approach includes novel constructions of copulas t...

It always gives me so much joy to watch parrots grip their favourite snacks like children eating ice cream cones.

My anti-research assistant, Dr Boris B. Bayes, PhD. His research interests include
(1) Optimal methods for screaming louder than 120dB,
(2) Finding excuses to bite, and
(3) Figuring out where fruit and almonds come from and how to make them appear on command.

Given 7-10 days to return a reviewer report from the day that I accepted the request... Not an MDPI journal. When did this become normal? Did it become normal?
