“You can’t stand on the beach of the sea of uncertainty with the waves lapping at your ankles.
You have to jump into the sea and stick your head underwater and blow some bubbles.”
- Andrew Gelman
I am an Associate Professor at the University of New South Wales. My research interests lie in the intersection of Bayesian statistics, econometrics and development economics. I am nonbinary and use they/them pronouns.
My papers are below. If you have a question about the code or data for any published paper please email me at r dot meager at unsw.edu.au
An R package 'baggr' for Bayesian evidence aggregation, co-authored with Witold Wiecek, is here on CRAN, or here on github, and a super short easy explainer is here
My CV is here (but less frequently updated than this website).
Any announcements are here.
You can usually find me on twitter or bsky. I also now have a blog/newsletter/thing where I write about art, emotions and death.
