Regardless of how the conversation with the OP unfolds, I'd be interested in your thoughts on this when you have time.  UNR should simply be a reparameterization of UN that yields the same model, but perhaps there are some cases where that breaks down?

Cheers,

I might take issue with using a "UNR" structure instead of
a "UN" structure to start but I'll save my reasoning for another time.
