return_type_t< T_y_cl, T_scale_succ_cl, T_scale_fail_cl > stan::math::beta_lpdf	(	const T_y_cl &	y,
		const T_scale_succ_cl &	alpha,
		const T_scale_fail_cl &	beta
	)

The log of the beta density for the specified scalar(s) given the specified sample stan::math::size(s).

y, alpha, or beta can each either be scalar or a vector on OpenCL device. Any vector inputs must be the same length.

The result log probability is defined to be the sum of the log probabilities for each observation/alpha/beta triple.

Prior sample sizes, alpha and beta, must be greater than 0.

Template Parameters

T_y_cl	type of scalar outcome
T_scale_succ_cl	type of prior scale for successes
T_scale_fail_cl	type of prior scale for failures

Parameters

y	(Sequence of) scalar(s).
alpha	(Sequence of) prior sample stan::math::size(s).
beta	(Sequence of) prior sample stan::math::size(s).

Returns

The log of the product of densities.
