WebDec 13, 2016 · 10. We use pm.Potential here primarily to get around the definition of a likelihood. We ordinarily use it to constrain our likelihood in the manner described in the PyMC docs, but in this example we never end up defining a true likelihood (which would require the inclusion of observations).
