Quantile-quantile Plot of T(n)Distribution. Quantile-quantile plot of the approximate normal distribution of T(n), the largest (order) GSMA statistic, under the correlation model (eqn. 2, with pairwise correlations ), x-axis, versus the independence model (eqn.1), y-axis. Following Wise , we chose n = 120. Quantiles are depicted from the .001 percentage point to the .999 percentage point.
