p = pd.Panel(data=np.zeros((2, 3, 3)))
p.mean(numeric_only=True)

NotImplementedError: Panel.mean does not implement numeric_only.
From the documentation it seems that pandas.Panel.mean should implement a numeric_only parameter - but it seems to be missing when numeric_only=True.

Comment From: jreback
yes it probably should, but Panel is deprecated so closing (though of course if you wanted to submit a PR to fix would prob accept).
