I’m just getting started with trying to use Gaussian processes. I have watched Statistical Rethinking 2023 - 16 - Gaussian Processes a few times and listened to some episodes on the Learning Bayesian Statistics where Gaussian processes were discussed. I also read through Gaussian Processes — PyMC 5…

Hi @Galen_Seilis , that’s a great question with an uncomfortable answer. I had the same question some years ago, and I ended up implementing a Matern kernel that used the Haversine distance (actually the grand-circle distance), and I had to dig deep to find out why my kernel gave back such huge CRAP. …
