Generation of Random Variates


James Huntley


generates random variates from over 870 univariate distributions

poislind_pdf(n, alpha)
% poislind_pdf.m - evaluates a Poisson Lindley Probability Density.

function [pdf] = poislind_pdf(n, alpha)

%persistent a2 ap1

    a2 = alpha^2;
    ap1 = alpha+1;

pdf = a2 * (alpha+2+n) / ap1^(n+3);
