double_exponential_lpdf() [2/3]

template<bool propto, typename T_y , typename T_loc , typename T_scale , require_all_not_nonscalar_prim_or_rev_kernel_expression_t< T_y, T_loc, T_scale > * = nullptr>

return_type_t< T_y, T_loc, T_scale > stan::math::double_exponential_lpdf	(	const T_y &	y,
		const T_loc &	mu,
		const T_scale &	sigma
	)

Returns the double exponential log probability density function.

Given containers of matching sizes, returns the log sum of densities.

Template Parameters

T_y	type of real parameter.
T_loc	type of location parameter.
T_scale	type of scale parameter.

Parameters

y	real parameter
mu	location parameter
sigma	scale parameter

Returns

log probability density or log sum of probability densities

Exceptions

std::domain_error	if y is nan, mu is infinite, or sigma is nonpositive
std::invalid_argument	if container sizes mismatch
