Generation of Random Variates


James Huntley (view profile)


generates random variates from over 870 univariate distributions

generr_cdf(x, nu, mu, sigma)
% generr_cdf.m - compute  Generalized Error Cumulative Distribution Function.
%   See "Cyclicality in Catastrophic and Operational Risk Measurements", 
%   L Allen and T.G. Bali, CUNY.              
%               Vector Form of CDF !!!
