I’ve recently learnt how to implement an n-level hierarchical model in PyMC3 from this post. In this example, all levels are nested (Global -> Degree -> State -> County). However, I’m trying to solve a problem that requires a mixture or nested and non-nested levels. For example, I might have something like (Global ->State -> County) and (Global -> Degree) in parallel. Is there a tutorial where I can learn how to implement this in PyMC3?
