`scipy.special:_poisson_binom_pmf`

source: build-install/usr/lib/python3.14/site-packages/scipy/special/__init__.py

Signature

def _poisson_binom_pmf(k, p, /, out = None, **kwargs)

Summary

Returns pmf of Poisson Binomial distribution.

Parameters

k : array: Number of successes at which to evaluate pmf.
p : array: Success probabilities of independent Bernoulli trials.

Notes

This is equivalent to a gufunc with signature ()(i)->(). The last dimension of p contains success probabilities and the preceding dimensions are batch dimensions. The batch dimensions are broadcast against k.

The output will be C contiguous regardless of the contiguity of k and p.
