dirichlet_log() [1/2]

template<bool propto, typename T_prob , typename T_prior_size >

return_type_t< T_prob, T_prior_size > stan::math::dirichlet_log	(	const T_prob &	theta,
		const T_prior_size &	alpha
	)

The log of the Dirichlet density for the given theta and a vector of prior sample sizes, alpha.

Each element of alpha must be greater than 0. Each element of theta must be greater than or 0. Theta sums to 1.

Deprecated:

use dirichlet_lpdf

Parameters

theta	A scalar vector.
alpha	Prior sample sizes.

Returns

The log of the Dirichlet density.

Exceptions

std::domain_error	if any element of alpha is less than or equal to 0.
std::domain_error	if any element of theta is less than 0.
std::domain_error	if the sum of theta is not 1.

Template Parameters

T_prob	Type of scalar.
T_prior_size	Type of prior sample sizes.
