Must produce a single value from an ndarray input if ``raw=True``

or a single value from a Series if ``raw=False``. Can also accept a

Numba JIT function with ``engine='numba'`` specified.
|
|
raw : bool, default False

* ``False`` : passes each row or column as a Series to the

function.

* ``True`` : the passed function will receive ndarray

objects instead.

If you are just applying a NumPy reduction function this will

achieve much better performance.
