Summary: [For the entire collection see Zbl 0741.00075.]
The nonparametric bootstrap and jackknife have been proven to be powerful tools for approximating the sampling distribution and variance of complicated statistics defined on a sequence of i.i.d. random variables. In the context of weakly dependent stationary observations, a block- resampling scheme was introduced by H. R. K√ľnsch [Ann. Stat. 17, No. 3, 1217-1241 (1989; Zbl 0684.62035)] and independently by R. Y. Liu and K. Singh in an unpublished manuscript, in order to obtain consistent bootstrap and jacknife procedures for a parameter of the \(m\)- dimensional joint distribution of the observations.
We discuss a ‘blocks of blocks resampling scheme’ that yields consistent procedures even for multivariate parameters of the whole (infinite- dimensional) joint distribution of stationary and \(\alpha\)-mixing observations. A notable example of such parameters is given by the spectral density function evaluated on a grid of points.
