Subsampling the Mean of Heavy-tailed Dependent ObservationsPiotr KokoszkaUtah State University - Department of Mathematics & Statistics Michael WolfUniversity of Zurich - Department of Economics Library; University of Zurich - Department of Eonomics Journal of Time Series Analysis, Vol. 25, No. 2, pp. 217-234, March 2004 Abstract: We establish the validity of subsampling confidence intervals for the mean of a dependent series with heavy-tailed marginal distributions. Using point process theory, we focus on GARCH-like time series models. We propose a data-dependent method for the optimal block size selection and investigate its performance by means of a simulation study.
