Enhancing the computational efficiency of the SGWR model and introducing its software implementation
Udgivet 2025-06-01Få fuldtekstThe SGWR model is a local spatial regression model that functions similarly to Geographically Weighted Regression (GWR) but incorporates a spatial weight matrix derived from both geographical proximity and data attributes similarity. The integration of these two weights is controlled by a parameter...
