I'm trying to implement the GP with a Poisson likelihood whose parameter may vary with the observations1:
$$ y_i \sim Poisson(e_i exp(f_i))$$
where f_i is the GP. Is this possible?

Hi,

It is not possible right now and having external parameters is something we haven't considered so far but definitely should!
