family for random coefficients in glmmADMB?

Hi All,

Apologies if this is an obvious question.  I have been playing with
some random coefficient count models using the glmmADMB package.  I
can specify the family for the response (poisson or negative binomial,
in my case), but I am wondering what distribution is assumed for the
random parameters?  I know it is common to use the conjugate prior of
the response family (gamma for poisson or beta for negative binomial),
but others are theoretically possible, no?

Looking through the documentation did not give me any hints (not to
say they were not there, but at least did not register for me).

Thanks!

Josh
