A combinatorial error bound for t-point-based sampling

The method of two-point-based sampling using orthogonal arrays (Inform. Process. Lett. 60 (1996) 91) is extended to consider t-wise independent sampling using orthogonal arrays of higher strength t. Using combinatorial considerations, an error bound is calculated which agrees with the previously known result when t = 2, and has the advantage of exponentially decreasing in t. The result is shown to be strictly sharper than that arising from the generalized Chebyshev inequality. Finally, the behavior of the family of error bounds we obtain for increasing values of t is analyzed.
