Requirements
-------------

To run correctly, scipy models requires the following:

        -python (>= 2.5): http://www.python.org tested with 2.5 and 2.6
        -numpy (>= 1.3.0) ?(>= 1.2.1) not tested http://www.scipy.org/Numpy
         tested with 1.5.1
        -scipy (>= 0.7 ?) http://www.scipy.org/ tested with 0.8 and 0.9
        -setuptools (easy_install): 
        http://peak.telecommunity.com/DevCenter/EasyInstall

On (X)ubuntu you can get the packages through 

apt-get install python python-setuptools python-numpy python-scipy

Optional Requirements:
----------------------

matplotlib: http://pypi.python.org/pypi/matplotlib required to build 
  sphinx documentation, for plot methods and it is used in examples
numdifftools: http://pypi.python.org/pypi/numdifftools used in the sandbox

Installing
-----------

Download and extract the source distribution, or branch from the repository.
In the statsmodels directory do:

python setup.py install

numpy 1.4.0 seems to require:
python setup.py build install

alternatively since statsmodels is a pure python package, it can be added
to the python path directly without installation
