Thanks for authoring a wonderful probabilistic programming language package. I was wondering if there any plans to add likelihoods for zero-inflated count data? E.g., ZIP (zero-inflated Poisson) and ZINB (zero-inflated negative binomial). Or is there a way to add custom likelihoods yourself?
Even if this means the means of inference becomes some sort of MCMC (e.g., HMC and its variants) it’d be a nice feature. PyMC3, btw, has ZIP support:
Many thanks ahead of time!
