Following discussion in #1728, I've had a go at creating a native Dirichlet multinomial family.
I've attempted to update the documentation of
brmsfamily
, and added some tests too.I'm not confident that the
posterior_epred.R
function is correct, and probably should not have included it.Hopefully this is helpful - please let me know if you need anything more from me. And thanks again @paul-buerkner for all your help with this!
