		const T_loc_cl &	mu,
		const T_scale_cl &	sigma
	)

Returns the double exponential log probability density function.

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

Template Parameters

T_y_cl	type of real parameter.
T_loc_cl	type of location parameter.
T_scale_cl	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
