The sentence "where 1 would mean the bucket [0, 100)" is wrong. It shoule be "where 1 would mean the bucket (0, 100]" Because `bins.searchsorted(np.array([100]))` return 1

There is no differences between Out[167] and Out[169]. Though I know the means, others maybe misunderstand this. So I recommend to change the In[168] to: `arr[:, 1].sort()`

Between In[114] and In[116] Should we add the In[115]? `In[115]: names = names.reset_index(drop=True)`

The trick can not work: ``` def demean_axis(arr, axis): means = arr.mean(axis) indexer = [slice(None)] * arr.ndim indexer[axis] = np.newaxis return arr - means[indexer] ``` Here is the way to...
