***************** | ||
About Statsmodels | ||
***************** | ||
|
||
Background | ||
---------- | ||
|
||
The ``models`` module of ``scipy.stats`` was originally written by Jonathan | ||
Taylor. For some time it was part of scipy but was later removed. During | ||
the Google Summer of Code 2009, ``statsmodels`` was corrected, tested, | ||
improved and released as a new package. Since then, the statsmodels | ||
development team has continued to add new models, plotting tools, and statistical methods. | ||
|
||
Testing | ||
------- | ||
|
||
Most results have been verified with at least one other statistical package: | ||
R, Stata or SAS. The guiding principal for the initial rewrite and for | ||
continued development is that all numbers have to be verified. Some | ||
statistical methods are tested with Monte Carlo studies. While we strive to | ||
follow this test driven approach, there is no guarantee that the code is | ||
bug-free and always works. Some auxiliary function are still insufficiently | ||
tested, some edge cases might not be correctly taken into account, and the | ||
possibility of numerical problems is inherent to many of the statistical | ||
models. We especially appreciate any help and reports for these kind of | ||
problems so we can keep improving the existing models. | ||
|
||
Code Stability | ||
~~~~~~~~~~~~~~ | ||
|
||
The existing models are mostly settled in their user interface and we do not | ||
expect many large changes going forward. For the existing code, although | ||
there is no guarantee yet on API stability, we have long deprecation periods | ||
in all but very special cases, and we try to keep changes that require | ||
adjustments by existing users to a minimal level. For newer models we might | ||
adjust the user interface as we gain more experience and obtain feedback. | ||
These changes will always be noted in our release notes available in the | ||
documentation. | ||
|
||
Financial Support | ||
----------------- | ||
|
||
We are grateful for the financial support that we obtained for the | ||
development of statsmodels: | ||
|
||
Google `www.google.com <http://www.google.com/>`_ : Google Summer of Code | ||
(GSOC) 2009-2013. | ||
|
||
AQR `www.aqr.com <http://www.aqr.com/>`_ : financial sponsor for the work on | ||
Vector Autoregressive Models (VAR) by Wes McKinney | ||
|
||
We would also like to thank our hosting providers, `github | ||
<http://github.com/>`_ for the public code repository, `sourceforge | ||
<http://sourceforge.net/>`_ for hosting our documentation and `python.org | ||
<http://python.org>`_ for making our downloads available on PyPi. |

Frequently Asked Question | ||
------------------------- | ||
|
||
.. _endog-exog-faq: | ||
|
||
What do endog and exog mean? | ||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | ||
|
||
These are shorthand for endogenous and exogenous variables. You might be more comfortable with the common ``y`` and ``X`` notation in linear models. Sometimes the endogenous variable ``y`` is called a dependent variable. Likewise, sometimes the exogenous variables ``X`` are called the independent variables. You can read about this in greater detail at :ref:`endog_exog` | ||
|
||
|
||
.. _missing-faq: | ||
|
||
How does statsmodels handle missing data? | ||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | ||
|
||
Missing data can be handled via the ``missing`` keyword argument. Every model takes this keyword. You can find more information in the docstring of :class:`statsmodels.base.Model`. | ||
|
||
.. `Model class <http://statsmodels.sourceforge.net/devel/dev/generated/statsmodels.base.model.Model.html#statsmodels.base.model.Model>`_. | ||
.. _build-faq: | ||
|
||
Why won't statsmodels build? | ||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | ||
|
||
If you're on Python 3.4, you *must* use Cython 0.20.1. If you're still having problems, try running | ||
|
||
.. code-block:: bash | ||
python setup.py clean | ||
What if my question isn't answered here? | ||
