摘要
We introduce a simple combinatorial scheme for systematically running through a complete enumeration of sample reuse procedures such as the bootstrap, Hartigan's subsets, and various permutation tests. The scheme is based on Gray codes which give 'tours' through various spaces, changing only one or two points at a time. We use updating algorithms to avoid recomputing statistics and achieve substantial speedups. Several practical examples and computer codes are given.
