Aesara/pymc automatically making non-centered parameterization in pymc 4.0?

Great job releasing pymc 4.0!

Anytime you use pm.Normal is it updated to non-centered?

If not, is there documentation on what parameterization is “automatically” updated to non-centered in 4.0?

No alternative parametrizations are automatically introduced at the moment.


In addition, I will note that both centered and non-centered hierarchical models can suffer from sampling issues (cite). So you should not assume that non-centered is universally superior.


Awesome citation! Thanks, I needed that!
