Sklearn transformers that work with Pandas dataframes

sklearn-pdtransform
-------------------

A little module with a few transformers to work with Pandas dataframes in the
Sklearn pipeline. Example usage:

.. code:: python
pipeline = Pipeline([
('ordinal_to_nums', DFTransform(_ordinal_to_nums, copy=True)),
('union', DFFeatureUnion([
('categorical', Pipeline([
('select', DFTransform(lambda X: X.select_dtypes(include=['object']))),
('fill_na', DFTransform(lambda X: X.fillna('NA'))),
('one_hot', DFTransform(_one_hot_encode)),
])),
('numerical', Pipeline([
('select', DFTransform(lambda X: X.select_dtypes(exclude=['object']))),
('fill_median', DFTransform(lambda X: X.fillna(X.median()))),
('add_features', DFTransform(_add_features, copy=True)),
('remove_skew', DFTransform(_remove_skew, copy=True)),
('find_outliers', DFTransform(_find_outliers, copy=True)),
('normalize', DFTransform(lambda X: X.div(X.max())))
])),
])),
])
