We prove concentration inequalities of the form P (Y ≥ t) ≤ exp(−B(t)) for a random variable Y with mean zero and variance σ using a coupling technique from Stein’s method that is so-called approximate zero bias couplings. Applications to the Hoeffding’s statistic where the random permutation has the Ewens distribution with parameter θ > 0 are also presented. A few simulation experiments are then provided to visualize the tail probability of the Hoeffding’s statistic and our bounds. Based on…
