":math:`\\\\chi^2` distribution.
Available constructors:
ChiSquare(*nu=1.0*)
Parameters
----------
nu : float, :math:`\\\\nu > 0`
Degrees of freedom.
Notes
-----
Its probability density function is defined as:
.. math::
f_X(x) = \\\\frac{2^{- \\\\nu / 2} x^{\\\\nu / 2 - 1} \\\\exp(- x / 2)}
{\\\\Gamma(\\\\nu / 2)}, \\\\quad x \\\\in \\\\Rset^{+*}
with :math:`\\\\nu > 0`.
Its first moments are:
.. math::
:nowrap:
\\\\begin{eqnarray*}
\\\\Expect{X} & = & \\\\nu \\\\\\\\
\\\\Var{X} & = & 2 \\\\nu
\\\\end{eqnarray*}
Examples
--------
Create a distribution:
>>> import openturns as ot
>>> distribution = ot.ChiSquare(2.)
Draw a sample:
>>> sample = distribution.getSample(10)"
// ---------------------------------------------------------------------
%feature("docstring") OT::ChiSquare::getNu
"Accessor to the degrees of freedom parameter.
Returns
-------
nu : float
Degrees of freedom."
// ---------------------------------------------------------------------
%feature("docstring") OT::ChiSquare::setNu
"Accessor to the degrees of freedom parameter.
Parameters
----------
nu : float, :math:`\\\\nu > 0`
Degrees of freedom."
