Hi! I'm a PhD student at the University of Groningen. See about for more information about me.

Most posts on this site are about statistics and programming and contain the code to reproduce the results. To reproduce newer posts, use the Pluto.jl notebook link at the bottom of the post. The source code for this website can be found at GitLab.
