Let :math:`y = {y_1}{y_2}` where :math:`y_1 = n_A + n_B - 2n_{AB}`, and :math:`y_2 = MED(A,B) \cdot n_B + MED(B,A) \cdot n_A`, with the mean-error distance (:math:`MED`) as described above, and where :math:`n_{A}`, :math:`n_{B}`, and :math:`n_{AB}` are the number of events within event areas *A*, *B*, and the intersection of *A* and *B*, respectively.

See :numref:`App_C-gbeta` for the :math:`G` and :math:`G_\beta` equations.

:math:`G_\beta` provides a summary measure of forecast quality for each user-defined threshold chosen. It falls into a range from zero to one where one is a perfect forecast and zero is considered to be a very poor forecast as determined by the user through the value of :math:`\beta`. Values of :math:`G_\beta` closer to one represent better forecasts and worse forecasts as it decreases toward zero. Although a particular value cannot be universally compared against any forecast, when applied with the same choice of :math:`\beta` for the same variable and on the same domain, it is highly effective at ranking such forecasts.
