return_type_t< T_size1, T_size2 > stan::math::beta_binomial_lpmf	(	const T_n &	n,
		const T_N &	N,
		const T_size1 &	alpha,
		const T_size2 &	beta
	)

Returns the log PMF of the Beta-Binomial distribution with given population size, prior success, and prior failure parameters.

Given containers of matching sizes, returns the log sum of probabilities.

Template Parameters

T_n	type of success parameter
T_N	type of population size parameter
T_size1	type of prior success parameter
T_size2	type of prior failure parameter

Parameters

n	success parameter
N	population size parameter
alpha	prior success parameter
beta	prior failure parameter

Returns

log probability or log sum of probabilities

Exceptions

std::domain_error	if N, alpha, or beta fails to be positive
std::invalid_argument	if container sizes mismatch
