Josef,
This is ticket #896 from two years ago. IIRC, there was some more recent discussion on the list of some of these. Do you know what the current state of these distributions is?
I don't have any information on these and I don't remember any discussion (and a quick search didn't find anything). I never looked at the integer overflow problem, besides reading the ticket. All 3 distributions are used in scipy.stats and tested for some regular values. (my not very strong opinion: for consistency with the other distributions, I would go with Robert's approach of rejecting overflow samples. I don't know any application where the truncation would have a significant effect. In scipy.stats I switched to returning floats instead of integers for ppf, because we need inf and nans.) BTW: If you are fixing things in np.random, then depreciating and renaming pareto as we discussed recently on the list would help reduce some confusion. I don't think we filed a ticket. Josef
