带测量误差的半函数型部分线性回归:一种基于$k$NN估计的方法

Semi-functional partial linear regression with measurement error: An approach based on $k$NN estimation

Silvia Novo, Germán Aneiros, Philippe Vieu

AI总结:

本文针对带测量误差的半函数型部分线性回归模型,提出基于$k$NN的估计方法,并给出渐近性质、模拟验证和真实数据应用。

摘要:

本文研究一种半参数回归模型,其中响应变量由两个分量之和解释。其一是参数(线性)分量,相应的解释变量带有加性误差且维数有限($p$);另一分量以非参数方式刻画函数型变量(无穷维)对响应变量的影响。针对每个分量提出了基于$k$NN的估计量,并得到了若干渐近结果。模拟研究展示了这些估计量在有限样本下的表现,而对真实数据的应用则表明了所提方法的实用性。

英文摘要:

This paper focuses on a semiparametric regression model in which the response variable is explained by the sum of two components. One of them is parametric (linear), the corresponding explanatory variable is measured with additive error and its dimension is finite ($p$). The other component models, in a nonparametric way, the effect of a functional variable (infinite dimension) on the response. $k$-NN based estimators are proposed for each component, and some asymptotic results are obtained. A simulation study illustrates the behaviour of such estimators for finite sample sizes, while an application to real data shows the usefulness of our proposal.
