Generation of Random Variates


James Huntley


generates random variates from over 870 univariate distributions

logisexp_pdf(x, bet, mu, alpha)
% logisexp_pdf.m - evaluates a Logistic Exponential Probability Density.

function [pdf] = logisexp_pdf(x, bet, mu, alpha)

%persistent coef

    coef = bet / alpha;

argx = exp((x-mu)/alpha);
pdf = coef .* argx .* (argx-1).^(bet-1) ./ (1+(argx-1).^bet).^2;
