Wrt the python package. Scipy has binomial and poisson classes [1,2]. I don't know if these fit the bill?

I think what he/she is looking for is the Poisson-Binomial distribution[1]. There is mention of one python package in the wikipedia article[2], but it doesn't seem to be widely used. There's an open issue from 2016 to implement it in scipy.stats[3].

Heh.

The attempt to shoehorn in the Python version of the R Fourier variation was closed 18 days ago with a "doesn't quite fit, try again later"

Thanks for the suggestions but unfortunately the poisson-binomial distribution [1] is not a simple combination of those two distributions. It requires of specialized packages like PoissonBinomial[2] in R.

Ahh my apologies. Shows my lack of domain knowledge.

Looking at some child comments it looks like there have been attempts to get it added to scipy since 2016.
