template<bool propto, typename T_n , typename T_N , typename T_x , typename T_alpha , typename T_beta , require_matrix_t< T_x > * = nullptr>

return_type_t< T_x, T_alpha, T_beta > stan::math::binomial_logit_glm_lpmf	(	const T_n &	n,
		const T_N &	N,
		const T_x &	x,
		const T_alpha &	alpha,
		const T_beta &	beta
	)

Returns the log PMF of the Generalized Linear Model (GLM) with Binomial distribution and logit link function.

The idea is that binomial_logit_glm_lpmf(n | N, x, alpha, beta) should compute a more efficient version of binomial_logit_lpmf(y | N, alpha + x * beta) by using analytically simplified gradients. If containers are supplied, returns the log sum of the probabilities.

Template Parameters

T_n	type of binary vector of successes variables; this can also be a single binary value;
T_N	type of binary vector of population size variables; this can also be a single binary value;
T_x	type of the matrix of independent variables (features)
T_alpha	type of the intercept(s); this can be a vector (of the same length as y) of intercepts or a single value (for models with constant intercept);
T_beta	type of the weight vector

Parameters

n	binary scalar or vector parameter. If it is a scalar it will be broadcast - used for all instances.
N	binary scalar or vector parameter. If it is a scalar it will be broadcast - used for all instances.
x	design matrix or row vector. If it is a row vector it will be broadcast - used for all instances.
alpha	intercept
beta	weight vector

Returns

log probability or log sum of probabilities

Exceptions

std::domain_error	if x, beta or alpha is infinite.
std::domain_error	if n is negative or greater than N
std::domain_error	if N is negative
std::invalid_argument	if container sizes mismatch.
