ON THE CHOICE OF m IN THE m OUT OF n BOOTSTRAP AND CONFIDENCE BOUNDS FOR EXTREMA

چکیده
For i.i.d. samples of size n, the ordinary bootstrap (Efron (1979)) is known to be consistent in many situations, but it may fail in important examples (Bickel, Götze and van Zwet (1997)). Using bootstrap samples of size m, where m → ∞ and m/n → 0, typically resolves the problem (Bickel et al. (1997), Politis and Romano (1994)). The choice of m is a key issue. In this paper, we consider an adaptive rule, proposed by Bickel, Götze, and van Zwet (personal communication), to pick m. We give general sufficient conditions for first order validity of the rule, and consider its higher order behavior when the ordinary bootstrap fails, and when it works. We then examine the behavior of the rule in the context of setting confidence bounds on high percentiles, such as the asymptotic expected maximum.

On the Choice of m in the m Out of n Bootstrap and its Application to Confidence Bounds for Extreme Percentiles
The m out of n bootstrap Bickel et al. [1997], Politis and Romano [1994] is a modification of the ordinary bootstrap which can rectify bootstrap failure when the bootstrap sample size is n. The modification is to take bootstrap samples of size m where m → ∞ and m/n→ 0. The choice of m is an important matter, in general. In this paper we consider an adaptive rule proposed by Bickel, Götze and va...
متن کاملNon-Bayesian Estimation and Prediction under Weibull Interval Censored Data
In this paper, a one-sample point predictor of the random variable X is studied. X is the occurrence of an event in any successive visits $L_i$ and $R_i$ :i=1,2…,n (interval censoring). Our proposed method is based on finding the expected value of the conditional distribution of X given $L_i$ and $R_i$ (i=1,2…,n). To make the desired prediction, our approach is on the basis of approximating the...
متن کاملBootstrap confidence intervals of CNpk for type‑II generalized log‑logistic distribution
This paper deals with construction of confidence intervals for process capability index using bootstrap method (proposed by Chen and Pearn in Qual Reliab Eng Int 13(6):355–360, 1997) by applying simulation technique. It is assumed that the quality characteristic follows type-II generalized log-logistic distribution introduced by Rosaiah et al. in Int J Agric Stat Sci 4(2):283–292, (2008). Discu...
متن کاملStatistical Topology Using the Nonparametric Density Estimation and Bootstrap Algorithm
This paper presents approximate confidence intervals for each function of parameters in a Banach space based on a bootstrap algorithm. We apply kernel density approach to estimate the persistence landscape. In addition, we evaluate the quality distribution function estimator of random variables using integrated mean square error (IMSE). The results of simulation studies show a significant impro...
متن کاملTie-respecting bootstrap methods for estimating distributions of sets and functions of eigenvalues
Bootstrap methods are widely used for distribution estimation, although in some problems they are applicable only with difficulty. A case in point is that of estimating the distributions of eigenvalue estimators, or of functions of those estimators, when one or more of the true eigenvalues are tied. The m-outof-n bootstrap can be used to deal with problems of this general type, but it is very s...
