There is a very crude guide in here: Probability Distributions in PyMC3 — PyMC3 3.10.0 documentation You have two options, to create a standard distribution by inheriting from the right subclasses (Discrete, Continuous, PositiveContinuous, etc), or using a pm.Densitydist that takes a callable logp …
