2007-12-02 Thread Chris
There appears to be a bug in numpy's hypergeometric random number generator. Here is an example -- if I generate 1000 hg samples with 4 draws from a space with 30 successes and 10 failures: In [39]: x = hg(30, 10, 4, 1000) I should get a mean value of: In [40]: 4*30./40 Out[40]: 3.0 But the
