Note: The ``$\chi_{a}^{2}$'' entries are the components of $\chi_{a}^{2}$
in (2), the ``$G^{2}$'' entries \\
are the analogous values of $-2\log$(likelihood ratio),
and $T_{GS}=T_{GS1}-T_{GS2}$ \\ is defined in (6).  The values 5.50,
19.36, and 1.25 should be compared to a $\chi_{3}^{2}$ distribution.
