shown that a bootstrap approximation to the sampling distribution of the weighted least squares estimate is valid, which …-sample properties of this new estimator as well as the improvements in performance realized by bootstrap confidence intervals. …

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

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 …
