%feature("docstring") OT::FisherSnedecor
"Fisher-Snedecor distribution.

Available constructors:
    FisherSnedecor(*d1=1.0, d2=5.0*)

Parameters
----------
d1 : float, :math:`d_1 > 0`
    First :class:`~openturns.ChiSquare` degrees of freedom (numerator).
d2 : float, :math:`d_2 > 0`
    Second :class:`~openturns.ChiSquare` degrees of freedom (denominator).

Notes
-----
Its probability density function is defined as:

.. math::

    f_X(x) = \frac{1}{x {\rm B}(d_1 / 2, d_2 / 2)}
             \left[\left(\frac{d_1 x}{d_1 x + d_2}\right)^{d_1 / 2}
                   \left(1 - \frac{d_1 x}{d_1 x + d_2}\right)^{d_2 / 2}\right],
             \quad x \in \Rset^{+*}

with :math:`d_1, d_2 > 0` and where :math:`\rm B` denotes Euler's beta
function.

Its first moments are:

.. math::
    :nowrap:

    \begin{eqnarray*}
        \Expect{X} & = & \frac{d_2}{d_2 - 2} \\
        \Var{X} & = & \frac{d_1 - 2}{d_1}\,\frac{d_2}{d_2 + 2}
    \end{eqnarray*}

Examples
--------
Create a distribution:

>>> import openturns as ot
>>> distribution = ot.FisherSnedecor(2.0, 3.0)

Draw a sample:

>>> sample = distribution.getSample(5)"
