where
z is the extreme value and μ, σ and ξ are the three parameters of the GEV model G(
z),
defining location, scale and shape parameters, respectively. This three-parameter distribution
unites the three possible extreme value distributions, namely type I (Gumbel), type II (Fréchet),
and type III (Weibull
