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 `_. .. _build-faq: Why won't statsmodels build? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ If you're on Python 3.4, you *must* use Cython 0.20.1.
