dnLaplace - Laplace Distribution
Laplace distribution with mean equal to ‘mean’ and scale equal to ‘scale’.
||Real (pass by const reference)
|The mean parameter.
|Default : 0
||RealPos (pass by const reference)
|The scale parameter.
|Default : 1
The Laplace distribution has density:
f(x) = 1/(2 b) e^-(abs(x-mu)/b)
where mu is the mean of the distribution and b the scale.
