Input-Output :mod:`iolib`
=========================

``statsmodels`` offers some functions for input and output. These include a
reader for STATA files, a class for generating tables for printing in several
formats and two helper functions for pickling.

Users can also leverage the powerful input/output functions provided by :ref:`pandas.io <pandas:io>`. Among other things, ``pandas`` (a ``statsmodels`` dependency) allows reading and writing to Excel, CSV, and HDF5 (PyTables).
