 On the error incurred using the bootstrap variance estimate when constructing confidence intervals for quantilesPeter Hall and Michael A. Martin Journal of Multivariate Analysis, 1991, vol. 38, issue 1, 70-81 Abstract: We show that the coverage error of confidence intervals and level error of hypothesis tests for population quantiles constructed using the bootstrap estimate of sample quantile variance is of precise order n-1/2 in both one- and two-sided cases. This contrasts markedly with more classical problems, where the error is of order n-1/2 in the one-sided case, but n-1 in the two-sided case, and results from an unusual feature of the Edgeworth expansion in that the leading term, of order n-1/2, is proportional to a polynomial containing both odd and even powers of the argument. Our results also show that for two-sided confidence intervals and hypothesis tests, and in large samples, the bootstrap variance estimate is inferior to the Siddiqui-Bloch-Gastwirth variance estimate provided the smoothing parameter in the latter is chosen to minimize coverage/level error.
