law0003.Cauchy: The Cauchy Distribution

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

Description

Random generation for the Cauchy distribution with parameters location and scale.

This generator is called by function gensample to create random variables based on its parameters.

Details

If location or scale are not specified, they assume the default values of 0 and 1 respectively.

The Cauchy distribution has density:

f(x) = 1 / (π s (1 + ((x-l)/s)^2))

where l is the location parameter and s is the scale parameter, for all x.
