[R] Vuong test

[Stéphanie PAYET]

Hi,

I have two questions. First, I'd like to compare a ZINB model to a negativ
binomial model with the Vuong test, but I can't find how to performe it from
the zicount package. Does a programm exist to do it ?
Second, I'd like to know in which cases we have to use a double hurdle model
instead of a zero inflated model.

Many thanks,

Stéphanie Payet
