our approach bootstrap fails in practice and theory. Instead, we propose a subsampling procedure with automatic parameter …

data in that period. To calculate asymptotically valid confidence intervals we use the delta method and two bootstrap …

The bootstrap is a convenient tool for calculating standard errors of the parameters of complicated econometric models …. Unfortunately, the fact that these models are complicated often makes the bootstrap extremely slow or even practically infeasible …. This paper proposes an alternative to the bootstrap that relies only on the estimation of one-dimensional parameters. The …
