Pascal
function GenExtValueCDF(x: double; k: double; Mu: double; sigma: double): double; overload;
Parameters 
Description 
Distribution domain, real value, valid if the relation k*(x-Mu)/sigma >-1 
Defines distribution shape parameter, real value. 
Mu 
Defines distribution location parameter, real value. 
sigma 
Defines distribution scale parameter, positive real value. 

the Generalized extreme value cumulative distribution function (CDF) for value x using the parameters k, Mu and sigma.
