%0 Journal Article %T The notion of $¦×$-weak dependence and its applications to bootstrapping time series %A Paul Doukhan %A Michael H. Neumann %J Mathematics %D 2008 %I arXiv %R 10.1214/06-PS086 %X We give an introduction to a notion of weak dependence which is more general than mixing and allows to treat for example processes driven by discrete innovations as they appear with time series bootstrap. As a typical example, we analyze autoregressive processes and their bootstrap analogues in detail and show how weak dependence can be easily derived from a contraction property of the process. Furthermore, we provide an overview of classes of processes possessing the property of weak dependence and describe important probabilistic results under such an assumption. %U http://arxiv.org/abs/0806.4263v1
