WebThe bootstrap, on the other hand, first estimates the whole distribution (of the point estimator) and then computes the variance from that. While powerful and easy, this can become highly computationally intensive. "The bootstrap can be applied to both variance and distribution estimation problems. WebIt is intuitive to construct bootstrap procedures that run forward in time, i.e., given X t 1, the next bootstrap observation is given by X t = ˚^ 1X t 1 + t; (2.1) and so on. Indeed, most (if not all) of the literature on bootstrap con dence intervals for AR models uses the natural time order to generate bootstrap series.
