This function generates Pareto random variables (of type I). See "Statistical Distributions", Evans, Hastings and Peacock, Wiley, 1993or http://www.maths.adelaide.edu.au/matthew.r...trns/node6.htmlor http://en.wikipedia.org/wiki/Pareto_distribution The Pareto distribution is a classic "heavy-tailed" or "power-law" distribution. It has distribution function F(x) = 1 - (b/x)^alpha, for x>=band density f(x) = (alpha/b) * (b/x)^(alpha+1), for x>=bIts mean is E[X] = b * alpha/(alpha-1), for alpha>1but note that the mean is infinite for alpha1but note that the variance is infinite for alpha=0, so to obtain this distributio just take x = randp(N,M,alpha,b) - b;
