In this case the hierarchy depth will be limited by the current value in state. This is probably not a good idea, as it might fluctuate to slightly larger values in the posterior. There is no performance penalty in increasing the hierarchy depth (within reason), as the the time it takes to update a hierarchy level with very few nodes/groups is negligible. -- Tiago de Paula Peixoto <[email protected]>
