I am happy I intrigued you enough that you decided to read it too! That's exactly why I posted a TLDR. I usually skim through comments before reading long articles, to check whether the article is interesting and worth my time. There was no comment so I made a bet and gave the article a try, as a payback to all the times other HN comments guided me to very interesting reads. About the time it took me to read the article, I read it during a break while working on some R code this afternoon. Based on the time of my commits, I can tell you it took me about 20 minutes. But I just went through the reasoning. I did not go into it very deeply or check the equations because mathematics is not my domain. I am in economics and IT (but going into statistics as it just seems more fun) I will also try to go over this article in more detail with a coffee in a few days as I found it very inspiring. Hopefully there will be more comments here to share some insights and act as a guide. Like, maybe a mathematician can spot errors in my summary, and suggest us something to read before this article to understand it better?
