The Laplace Distribution
Description
Random generation for the Laplace distribution with parameters mu
and b
.
This generator is called by function gensample
to create random variables based on its parameters.
Details
If mu
or b
are not specified they assume the default values of 0 and 1, respectively.
The Laplace distribution has density:
\frac{1}{2b}\exp \left( -\frac{|x-\mu|}{b} \right)
where \mu
is a location parameter and b
> 0, which is sometimes referred to as the diversity, is a scale parameter.
