characterize their quantile breakdown point. For the moving block bootstrap and the subsampling, we find a very low quantile …We study the robustness of block resampling procedures for time series. We first derive a set of formulas to … breakdown point. A similar robustness problem arises in relation to data-driven methods for selecting the block size in …

This paper considers an empirical likelihood method to estimate the parameters of the quantile regression (QR) models … regression models. Our results are extensions of the previous results of Chen and Hall (1993) to the regression contexts. Monte … than the confidence regions that can be constructed from the smoothed bootstrap method recently suggested by Horowitz (1998) …

This paper develops a specification test for instrument validity in the heterogeneous treatment effect model with a binary treatment and a discrete instrument. The strongest testable implication for instrument validity is given by the condition for nonnegativity of point-identifiable complier's...

In an attempt to free bootstrap theory from the shackles of asymptotic considerations, this paper studies the … possibility of justifying, or validating, the bootstrap, not by letting the sample size tend to infinity, but by considering the … sequence of bootstrap P values obtained by iterating the bootstrap. The main idea of the paper is that, if this sequence …

As I document using evidence from a journal data repository that I manage, the datasets used in empirical work are getting larger. When we use very large datasets, it can be dangerous to rely on standard methods for statistical inference. In addition, we need to worry about computational issues....

This paper shows how to bootstrap hypothesis tests in the context of the Parks (Efficient estimation of a system of … regression equations when disturbances are both serially and contemporaneously correlated 1967) estimator. It then demonstrates … that the bootstrap outperforms Parks's top competitor. The Parks estimator has been a workhorse for the analysis of panel …

This paper shows how to bootstrap hypothesis tests in the context of the Parks’s (1967) Feasible Generalized Least … Squares estimator. It then demonstrates that the bootstrap outperforms FGLS(Parks)’s top competitor. The FGLS(Parks) estimator … has been a workhorse for the analysis of panel data and seemingly unrelated regression equation systems because it allows …
