摘要:

本文考虑空间数据半参数变系数分位数回归的一种估计。一个通用的强大的框架,对待分位数回归空间数据的自然半参数的方式。利用局部线性逼近,给出了未知函数系数函数的局部M-估计,并在弱空间混合条件下建立了其渐近分布.土壤数据集的应用证明了有趣的发现,超越传统的分析。

英文摘要:

This paper considers an estimation of semiparametric functional (varying)-coefficient quantile regression with spatial data. A general robust framework is developed that treats quantile regression for spatial data in a natural semiparametric way. The local M-estimators of the unknown functional-coefficient functions are proposed by using local linear approximation, and their asymptotic distributions are then established under weak spatial mixing conditions allowing the data processes to be either stationary or nonstationary with spatial trends. Application to a soil data set is demonstrated with interesting findings that go beyond traditional analysis.
