空间多观测样本的地理加权回归模型
Geographically Weighted Regression for Spatial Data with Replicates
摘要
Abstract
The paper extends the classical GWR and constants a multiple replicates geographically weighted regression(MRGWR)that is able to handle an arbitrary number of replicates at each individual location.MRGWR adequately utilizes the similarity of regression relationships at neighboring locations when estimating regression coefficients,and imposes different weights on the replicates at neighboring locations.Moreover,it can directly handle the case of arbitrary number of replicates at each location.Numerical experiments are conducted to estimate the performance of the proposed model and to compare with ordinary least squares regression(OLSR)and GWR models.Furthermore,MRGWR is applied to resolving an important scientific problem in oceanography,i.e.,the ocean mesoscale eddy thermal feedback,revealing the seasonal and spatial variations in the response relationship between mesoscale sea surface heat flux anomalies and mesoscale sea surface temperature(SST)anomalies in the North Pacific.关键词
