The nanmedian function in Bottleneck 0.4.3 contains a bug.
The output of nanmedian is wrong for particular orderings of NaN and
non-NaN elements.
Wrong:
>> bn.nanmedian([1, np.nan, np.nan, 2])
1.0
Right:
>> bn.nanmedian([1, 2, np.nan, np.nan])
1.5
>> bn.nanmedian([1, np.nan, 2, np.nan])
1.5
The bug has been fixed in Bottleneck 0.5.0dev [1].
