Also it seems that pilots-pilots posterior in its current form is a bit problematic. With method_arguments = list(chains = 10, iter = 30000, warmup = 20000, thin = 10, seed = 4711, control = list(adapt_delta = 0.99, max_treedepth = 15))), There are a couple hundred divergent transitions after warmup and the max_treedepth gets exceeded. Maybe a (non-centered) reparametrization could be in order here? @paul-buerkner @avehtari

I agree it's problematic and should be investigated. We want to have some difficult posteriors in db, too, but 1) it would be good to still have a good reference posterior draws, 2) if good reference posterior draws are not available, then the reference should be empty.
