law0001.Laplace: The Laplace Distribution

In PoweR: Computation of Power and Level Tables for Hypothesis Tests

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:

f(x) = (1/2b) e^-(|x - μ|/b)

where μ is a location parameter and b > 0, which is sometimes referred to as the diversity, is a scale parameter.
