Hello,

I had a quick question about the interface for hierarchal models; are hierarchal models supported in BayesFlow V2? I remember there were several methods in V1 that supported hierarchal models. If so, how would you go about specifying the priors and the sampling?

Thanks!

Hey Wei, for now we should use v1 for hierarchical models. V2 will soon include a much more general interface for arbitrary hierarchical models.
