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 between two independent, and equally distributed, exponents. It is also used in error analysis.

Example

phi = 1; theta = 0

laplace(double phi, double theta)

Description
Generates a sample of the Laplace distribution.
