用于条件均值根号样本量一致估计的去偏回归

研究问题
对于高维或非参数回归估计量,能否通过可计算的偏差修正获得根号样本量一致性和渐近正态性,以支持区间推断?
方法与思路
作者扩展半参数一步估计思路,估计原始回归残差的条件期望并加入修正项,该条件期望可用核回归等方法估计。
材料陈述的贡献
摘要称在原估计量与条件残差期望估计量满足一定收敛速度条件时,修正估计具有根号样本量一致性和渐近正态性。
阅读关注点
应核对条件均值的具体目标、评价位置和渐近框架,以及两类估计的速度要求、样本使用方式与方差估计。
阅读边界
所据版本为 arXiv 预印本,同行评审及期刊接收未核实;摘要未写明速度条件及估计对象细节,不能推广为任意条件均值均可实现该速率。

原文摘要

This study introduces a debiasing method for regression estimators, including high-dimensional and nonparametric regression estimators. For example, nonparametric regression methods allow for the estimation of regression functions in a data-driven manner with minimal assumptions; however, these methods typically fail to achieve $\sqrt{n}$-consistency in their convergence rates, and many, including those in machine learning, lack guarantees that their estimators asymptotically follow a normal distribution. To address these challenges, we propose a debiasing technique for nonparametric estimators by adding a bias-correction term to the original estimators, extending the conventional one-step estimator used in semiparametric analysis. Specifically, for each data point, we estimate the conditional expected residual of the original nonparametric estimator, which can, for instance, be computed using kernel (Nadaraya-Watson) regression, and incorporate it as a bias-reduction term. Our theoretical analysis demonstrates that the proposed estimator achieves $\sqrt{n}$-consistency and asymptotic normality under a mild convergence rate condition for both the original nonparametric estimator and the conditional expected residual estimator. Notably, this approach remains model-free as long as the original estimator and the conditional expected residual estimator satisfy the convergence rate condition. The proposed method offers several advantages, including improved estimation accuracy and simplified construction of confidence intervals.
