return_type_t< T_y, T_scale, T_shape > stan::math::loglogistic_lpdf	(	const T_y &	y,
		const T_scale &	alpha,
		const T_shape &	beta
	)

The log of the loglogistic density for the specified scalar(s) given the specified scales(s) and shape(s).

y, alpha, or beta can each be either a scalar or a vector. 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/scale/shape triple.

Template Parameters

T_y	type of scalar.
T_scale	type of scale parameter.
T_shape	type of shape parameter.

Parameters

y	(Sequence of) scalar(s).
alpha	(Sequence of) scale parameter(s) for the loglogistic distribution.
beta	(Sequence of) shape parameter(s) for the loglogistic distribution.

Returns

The log of the product of the densities.

Exceptions

std::domain_error

if any of the inputs are not positive and finite.
