Generation of Random Variates


James Huntley


generates random variates from over 870 univariate distributions

zip_cdf(n, omega, lambda)
% zip_cdf.m - compute Zero-Inflated Poisson Cumulative Distribution Function.
%   See "Models for Count Data with Many Zeros",

function [cdf] = zip_cdf(n, omega, lambda)

sum1 = zip_pdf(0, omega, lambda);
for jn = 1:n
    sum1 = sum1 + zip_pdf(jn, omega, lambda);
cdf = sum1;
