Combined p-Values

The test statistic is:

[math]\displaystyle{ X^2 = -2\sum^k_{i=1} \log p_i }[/math]

where:

[math]\displaystyle{ p_i }[/math] is the p-Value of the [math]\displaystyle{ i }[/math]th of [math]\displaystyle{ k }[/math] tests, and

[math]\displaystyle{ p = \Pr(\chi^2_{2k} \ge X^2) }[/math]
