WebThe proposed method can be extended to time-series data when considering pure nonlinear autoregressive dependence structures. In this latter case, the pair bootstrap can deliver consistent estimators for the involved sampling distribution in the inferential steps . This is part of a different line of research that is still under investigation. WebThe paper is organized as follows. Section 2 introduces the sieve bootstrap for estimating forecast intervals. Section 3 presents a Monte Carlo study comparing the nite sample properties of the sieve bootstrap with those of alternative methods. We show that the average coverage is better when intervals are constructed incorporating
