I don't understand this discussion at all. n random numbers constrained to have sum <=1 are still random. They are not all independent.
That said, the original poster's question is ill=formed since there can be multiple distributions these random numbers come from. best wishes, Ranjan On Sat, 22 Nov 2014 10:29:18 -0500 Boris Steipe <boris.ste...@utoronto.ca> wrote: > These are contradictory requirements: either you have n random numbers from > the interval [0,1), then you can't guarantee anything about their sum except > that it will be in [0,n).
