Aight, so here it is: https://github.com/torfjelde/Prophet.jl
It’s in a very raw form atm, but at least it’s something we can work with. We might want to make it more similar to Python’s prophet, but atm it’s just the bare bones to get up and running with inference.
It’s also missing certain functionalities, e.g. using logit-likelihood, etc., which I just haven’t gotten around to yet, but will be trivial to add.
