The aim of this paper is to investigate the impacts of wind farms on the surrounding area through property values, by means of a hedonic pricing model, using both a spatial fixed (viewshed) effects (accounting for spatially clustered unobserved influences) and a geographically weighted regression model (accounting for spatial heterogeneity. While the linear regression model was found to be signifi cant and had a strong r-squared value of 0782 (p = 0000), the gwr model improved on these statistics and increased the model's accuracy to an r-squared value of 0865 (p = 0000.
Geographically weighted regression (gwr) is a modelling technique designed to deal with spatial non-stationarity, eg, the mean values vary by locations it has been widely used as a visualization tool to explore the patterns of spatial data.

In this paper, we compare two approaches to examine spatial heterogeneity in housing attribute prices within the tucson, arizona housing market: the spatial expansion method and geographically weighted regression (gwr. Geographically weighted regression (gwr) is an important local technique for exploring spatial heterogeneity in data relationships in fitting with tobler's first law of geography, each local regression of gwr is estimated with data whose influence decays with distance, distances that are commonly defined as straight line or euclidean.
