The Generalized Extreme Value Distribution

Share:

Description

Random generation for the Generalized Extreme Value 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 1, respectively.

The Generalized Extreme Value distribution with parameters mu = μ, sigma = σ and xi = ξ has density:

f(x) = (1 + z)_{+}^{-1/ξ - 1} {e^[(1 + z)_{+}^{-1/ξ}]}/σ

for ξ > 0 or ξ < 0, where z = ξ (x - μ)/σ. If ξ = 0, PDF is as same as in the Gumbel distribution.
