摘要
地理加权回归作为一类能有效处理回归分析中空间非平稳性现象的建模技术,在多类问题的研究得到了广泛的应用.主要讨论这类空间计量经济学模型在空间自相关情形下的估计问题.首先,对于因变量含有空间滞后项的地理加权回归模型,分别给出了局部似然估计和两步估计两种方法.其次,考虑了误差空间自相关下地理加权回归模型的估计问题.
Geographically weighted regression(GWR),as a useful method for exploring spatial non- stationarity of a regression relationship,has been applied to a variety of areas. In this paper,This paper considers the estimation of this spatial economtrics model when spatial autocorrelation is available.Firstly,we propose a geographically weighted autogressive models and provide local likelihood and two-step method estimating procedures.Secondly, the estimation of geographically weighted regression model's with spatial correlated errors is discussed.
