Difference between pm.Poisson(.) and pm.Poisson.dist(.)

Hi all,

Can you shed some light on what’s the difference between Poisson and Possion.dist. I’ve tried to find the description of the latter without luck.

Also, how can I name them. When trying something like: pm.Posson.dist(‘myPoisson’, mu=mu) I get an error. I’ve seen some examples like this and none of them name it. Is it because it can’t be named?
