I think the correct solution is actually to alter the mean (and optionally the variance) to get things to a level we want. I don't see anything wrong with an algorithm with infinite range as long as it works. EDIT: Doing a bit of research, some distributions don't have a variance, so maybe that is what infinite variance means. I haven't looked at the actual method used yet, but I do know of distributions which have infinite range but have a mean and a variance (the exponential distribution, for instance). I am not some kind of statistics expert though so people should feel free to correct me if I'm wrong. __________________ linux->xterm->screen->pmacs Last edited by d_m; December 21, 2010 at 17:03.
