Detailed Description

Binomial(n, p) family implementation (discrete).

A discrete, integer-valued family in the otherwise-continuous Distribution hierarchy, instantiated only for a latent (token-parameterised) leaf – provsql.binomial(integer, random_variable) – the literal constructor enumerates an exact categorical instead. As for poisson, a parametric leaf is declined by parse_distribution_spec, so no continuous-analytic path integrates its pdf as a density: it is reached only by the Monte Carlo sample(), by observe (weight pdf = pmf at the datum), and by the moment path.

p1 = n (number of trials), p2 = p (success probability).
