The pdf of the inverse gamma distribution is defined as follows:
.. math ::
\\frac{q^\\alpha}{\\Gamma(\\alpha)}x^{-\\alpha -1}\\exp \\left(-\\frac{q}{x}\\right)
.. math::
\\frac{q^\\alpha}{\\Gamma(\\alpha)}x^{-\\alpha -1}
\\exp \\left(-\\frac{q}{x}\\right)
That means that for large x the pdf falls off like :math:`x^(-\\alpha -1)`.
The mean of the pdf is at :math:`q / (\\alpha - 1)` if :math:`\\alpha > 1`.
