[R-sig-ME] fitting beta and zero mixture model containing both nested and crossed random effects

[Guillaume Chaumet]

My bad, I replied to you the first time without including the list.
Regarding your last question, perhaps the list and/or Ben could
provide a more accurate answer than me.
I'm also curious to know how glmmTMB could do that
