i = l "i = l
for some constants Xi and x2.
If the size of the test is a (0 < a < I), you can find x^ and x2 by
solving the system of equations/^(x) = /2(x) = 0, where
= (n - 1) \n(x2/xl) + xl - x2

J /2(x)=J (w/2)mexp(-w/2)dw - 2(1 -a)T(m + 1).
•*-!
Here ^2 ^ ^i > 0, a and n are known (n > 1), and m = (n — l)/2 — 1.
An initial guess for (x1,x2) is
and ^ = Xn2__a/2
where xjp is thepth percentile of the chi-square distribution with d
degrees of freedom.
For this example,
