When homogeneity meets heterogeneity: the geographically weighted regression with spatial lag approach to prenatal care utilisation

open access: yesGeospatial Health, 2014
Using geographically weighted regression (GWR), a recent study by Shoff and colleagues (2012) investigated the place-specific risk factors for prenatal care utilisation in the United States of America (USA) and found that most of the relationships ...

A Spatial Analysis of Disposable Income in Ireland: A GWR Approach

open access: yes, 2020
This paper examines the spatial distribution of income in Ireland. Median gross household disposable income data from the CSO, available at the Electoral Division (ED) level, is used to explore the spatial variability in income. Geary's C highlights the spatial dependence of income, highlighting that the distribution of income is not random across ...

Comparison between Kriging and GWR for the Spatial Data

open access: yesKorean Journal of Applied Statistics, 2005
Kriging methods as traditional spatial data analysis methods and geographical weighted regression models as statistical analysis methods are compared. In this paper, we apply data from the Ministry of Environment to spatial analysis for practical study.

Bayesian geographically weighted regression and its application for local modeling of relationships between tree variables

open access: yesiForest - Biogeosciences and Forestry, 2018
Geographically weighted regression (GWR) has become popular in recent years to deal with spatial autocorrelation and heterogeneity in forestry and ecological data. However, researchers have realized that GWR has some limitations, such as correlated model

Geographically Varying Coefficient Regression: GWR-Exit and GAM-On? (Short Paper).

open access: yes, 2022
This paper describes initial work exploring two spatially varying coefficient models: multi-scale GWR and GAM Gaussian Process spline parameterised by observation location. Both approaches accommodate process spatial heterogeneity and both generate outputs that can be mapped indicating the nature of the process heterogeneity.
