law0023.GeneralizedPareto: The Generalized Pareto Distribution

Description

Random generation for the Generalized Pareto distribution with parameters mu, sigma and xi.

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

Details

If mu, sigma and xi are not specified they assume the default values of 0, 1 and 0, respectively.

The Generalized Pareto distribution with parameters mu = $\mu$, sigma = $\sigma$ and xi = $\xi$ has density: $$\frac{1}{\sigma }{(1+\frac{\xi (x-\mu )}{\sigma })}^{(-\frac{1}{\xi }-1)}$$ where $x\ge \mu$ if $\xi \ge 0$ and $x\le \mu -\sigma /\xi$ if $\xi <0$.
