For quite a while now I was hoping that at some point I’d be able to publish a paper together with my father, but up to now our respective fields of work were too divergent.
Some time ago, he asked me for help on figuring out some multi-dimensional integrals, because he believed that a measure of the structural diversity in Plenter-forests called the Gini-coefficient (Gini 1912; H. Sterba and Zingg 2006; Katholnig 2012) that is usually measured could be analytically calculated. Turns out, he was right! From this discussion and some work on those integrals we were able to write up his thoughts (J. H. Sterba and Sterba 2018) and come up with an equation that makes it possible to calculate the Gini-coefficient directly from some parameters.
I’m very happy that we managed to get this paper published and I now have a Sterba and Sterba publication to my name!
