Webi) is also the value of the probability distribution function of the test statistic and therefore it is uniformly distributed on the interval [0, 1]. This holds for any continuous test statistic. Moreover, 2lnp i has a chi-square distribution with two degrees of freedom. This led Fisher [1932] to note that the statistic t = 2 XL i=1 lnp i= 2ln ...
