laplace
The Laplace distribution, sometimes called the double exponential
distribution, is an unbounded continuous distribution that has a very
sharp central peak, located at theta. The distribution scales with phi.
The Laplace distribution can be used to describe the difference of two
independent, and equally distributed, exponentials. It is also used in
error analysis.
