return_type_t< T_y_cl, T_loc_cl, T_scale_cl > stan::math::lognormal_lpdf	(	const T_y_cl &	y,
		const T_loc_cl &	mu,
		const T_scale_cl &	sigma
	)

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

y, mu, or sigma 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/mu/sigma triple.

Template Parameters

T_y_cl	type of scalar outcome
T_loc_cl	type of prior scale for successes
T_scale_cl	type of prior scale for failures

Parameters

y	(Sequence of) scalar(s).
mu	(Sequence of) prior sample stan::math::size(s).
sigma	(Sequence of) prior sample stan::math::size(s).

Returns

The log of the product of densities.
