fyi, numpy 1.8 will in future also implement nanmean which scipy will then use. But note that numpy.nanmean will alos warn if you use it on an array full of nans:
In [1]: np.nanmean([np.nan, np.nan]) /tmp/local/lib/python2.7/site-packages/numpy/lib/nanfunctions.py:573: NanWarning: Mean of empty slice warnings.warn("Mean of empty slice", NanWarning) Out[1]: nan In [2]: np.__version__ Out[2]: '1.8.0.dev-410ad54' -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
