Generation of Random Variates


James Huntley


generates random variates from over 870 univariate distributions

betawarn_cdf(x, b, m, n, nu1, nu2)
% betawarn_cdf.m - compute Beta Warning Time Cumulative Distribution Functions.
%   See "Continuous Univariate Distributions", Johnson, Kotz, and
%   Balakrishnan, V2, J. Wiley, , p.350, 1996.               
%               Vector Form of CDF !!!
%  Created by:  Jim Huntley,  11/17/06.

function [cdf] = betawarn_cdf(x, b, m, n, nu1, nu2)

% Integrate PDF to get CDF.
dx = x(2) - x(1);
pdf = betawarn_pdf(x, b, m, n, nu1, nu2);
for jz = 1:size(x,2);
    cdf(jz) = trapz(pdf(1:jz)) * dx;
