Quantile–quantile plot of p values from Epps–Singleton tests comparing the two distributions. The null hypothesis is that the two distributions are identical. Under the null hypothesis, the p value is uniformly distributed and we would expect the Q–Q plot to be linear along the diagonal, which is what we observe. The count table distributions generated from each method are indistinguishable via this test
