What are the corresponding objective function names?
The poisson
objective function is already supported:

I haven't tried poisson
explicitly.
I assumed poisson
wasn't implemented because I've tried gamma
and tweedie
which weren't implemented and they all belong to the exponential family of distributions.
The objective names are gamma
and tweedie
.
