Bias-corrected bootstrap,即偏差校正自助法,是一种改进的自助法(bootstrap)技术,用于估计统计量的分布及其置信区间。传统的自助法通过从原始样本中重复抽样(有放回抽样)来生成多个自助样本,从而估计统计量的分布。然而,传统自助法有时会产生偏差,特别是在样本量较小或统计量的分布不对称时。偏差校正自助法则通过调整...
bias-corrected bootstrap method bias-corrected bootstrap method(偏差校正自助法)是一种统计学方法,用于估计统计量的偏差并进行校正。该方法主要用于通过自助抽样的方式来重复抽样数据集,并通过计算抽样数据集的统计量来估计原始数据集的统计量。本文将逐步解释bias-corrected bootstrap method的基本概念、步骤和应用。
1. Bootstrap Bias Correction: - Bootstrap方法是一种通过重复抽样来估计统计量分布的技术。在"bias-corrected" bootstrap中,通过对样本进行多次重抽样,生成多个估计值的分布,并计算其平均值或中位数,以纠正原始估计的偏差。 2. Heteroscedasticity Bias Correction: -当观测数据的方差不是恒定的时候,会引入异方差性...
bias-corrected bootstrap method -回复 (假设读者已经有一定的统计学基础知识) 介绍: 假设检验是统计学中非常重要的概念之一,用于判断在某种假设条件下,观测数据与假设是否一致。然而,传统的假设检验方法在某些情况下可能会出现一些问题,比如数据的分布非常偏斜或假设条件不满足时。为了克服这些问题,可以使用一种被称为...

the bootstrap procedure also involves various problems (e.g., cf. [4] for anoverview). For instance, in the non-parametric bootstrap, where bootstrap samplesD (b) (b = 1,...,B) are generated by drawing the data points from the given data Dwith replacement, each bootstrap sample D...
This paper examines small sample properties of alternative bias-corrected bootstrap prediction regions for the vector autoregressive (VAR) model. Bias-corrected bootstrap prediction regions are constructed by combining bias-correction of VAR parameter estimators with the bootstrap procedure. The backward VA...
