In [12]: sp.nanstd(a, axis=-1)
---------------------------------------------------------------------------
ValueError Traceback (most recent call last)
/home/fab/<ipython console> in <module>()
/usr/lib/python2.6/dist-packages/scipy/stats/stats.pyc in nanstd(x, axis, bias)
302 if axis!=0:
303 shape = np.arange(x.ndim).tolist()
--> 304 shape.remove(axis)
305 shape.insert(0,axis)
306 x = x.transpose(tuple(shape))
ValueError: list.remove(x): x not in list
In fact -1 is not in the generated list (l303)
See http://projects.scipy.org/scipy/ticket/1161 (closed), but the fix
did not reach my machine by now...
