The parameters are estimated by method of moments:

.. math::
    :nowrap:

    \begin{eqnarray*}
      \displaystyle\Hat{\alpha} =\frac{\pi}{\Hat{\sigma}_x\sqrt{6}}\\
      \displaystyle\Hat{\beta} =\bar{x}_n-\frac{\gamma\sqrt{6}}{\pi}\Hat{\sigma}_x\\
    \end{eqnarray*}

with :math:`\gamma \simeq 0.57721` as Euler's constant.
