摘要:

本文为自助法均值等随机加权和建立了新颖的强一致大数定律。借助最新进展,这些结果在广泛的加权程序适用性及对有效自助法样本量的灵活性方面扩展了先前的工作。除标准多项式自助法和m-out-of-n自助法外,我们的结果适用于一大类涉及负正交相依(NOD)权重的随机加权和,包括Bayesian自助法、刀切法、无放回重抽样、超放回简单随机抽样、独立权重及多元高斯加权方案。权重允许非同分布甚至为负。我们的证明技术基于将独立同分布强一致大数定律的证明扩展以利用随机加权和的强定律;特别地,我们利用了近期关于NOD加权和的Marcinkiewicz-Zygmund强定律。

英文摘要:

This article establishes novel strong uniform laws of large numbers for randomly weighted sums such as bootstrap means. By leveraging recent advances, these results extend previous work in their general applicability to a wide range of weighting procedures and in their flexibility with respect to the effective bootstrap sample size. In addition to the standard multinomial bootstrap and the m-out-of-n bootstrap, our results apply to a large class of randomly weighted sums involving negatively orthant dependent (NOD) weights, including the Bayesian bootstrap, jackknife, resampling without replacement, simple random sampling with over-replacement, independent weights, and multivariate Gaussian weighting schemes. Weights are permitted to be non-identically distributed and possibly even negative. Our proof technique is based on extending a proof of the i.i.d. strong uniform law of large numbers to employ strong laws for randomly weighted sums; in particular, we exploit a recent Marcinkiewicz--Zygmund strong law for NOD weighted sums.
