For i.i.d. samples of size n, the ordinary bootstrap (Efron (1979)) is known to be consistent in many situations, but it may fail in important examples (Bickel, Gotze and van Zwet (1997)). Using bootstrap samples of size m, where m ! 1 and m/n ! 0, typically resolves the problem (Bickel et al. (1997), Politis and Romano (1994)). The choice of m is a key issue. In this paper, we consider an adaptive rule, proposed by Bickel, Gotze, and van Zwet (personal communication), to pick m. We give general sufficient conditions for first order validity ofthe rule, and consider its higher order behavior when the ordinary bootstrap fails, and when it works. We then examine the behavior of the rule in the context of setting confidence bounds on high percentiles, such as the asymptotic expected maximum.
