-``apply`` on a Series can operate on a returned value from the applied function
-that is itself a series, and possibly upcast the result to a DataFrame:

 Similar to :ref:`groupby.aggregate.agg`, the resulting dtype will reflect that of the
 apply function. If the results from different groups have different dtypes, then
 a common dtype will be determined in the same way as ``DataFrame`` construction.
