[Numpy-discussion] cov

[Alan G Isaac]

1. Should `numpy.cov` use `ddof` instead of `bias`,
like `std` and `mean`?

2. Should the docs for scipy.cov state that it is deprecated?
http://docs.scipy.org/scipy/docs/scipy.stats.stats.cov/#scipy-stats-cov
(Use raises a deprecation warning.)

Thanks,
Alan Isaac
