inline

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

y, alpha, 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/alpha/sigma triple.

Template Parameters

T_y_cl	type of scalar outcome
T_shape_cl	type of shape
T_scale_cl	type of scale

Parameters

y	(Sequence of) scalar(s).
alpha	shape
sigma	scale

Returns

The log of the product of densities.
