www.elsevier.com/locate/jspi The local bootstrap for Markov processes

A nonparametric bootstrap procedure is proposed for stochastic processes which follow a gen-eral autoregressive structure. The procedure generates bootstrap replicates by locally resampling the original set of observations reproducing automatically its dependence properties. It avoids an initial nonparametric estimation of process characteristics in order to generate the pseudo-time series and the bootstrap replicates mimic several of the properties of the original process. Ap-plications of the procedure in nonlinear time-series analysis are considered and theoretically justi.ed; some simulated and real data examples are discussed
