[Numpy-discussion] numpy.random.geometric is shifted

2014-02-25 Thread Alan G Isaac 
Just got momentarily snagged by not checking the
excellent documentation, which clearly says that
numpy provides the shifted geometric.  I'm wondering
why? Who else does?  (Not Mathematica, Matlab, Maple,
or Octave.)

Thanks,
Alan Isaac

As with most such questions, because the reference I was working from
defined it that way and gave the algorithms with that convention.
