Spatial nonstationarity
Web22. mar 2024 · The concept of spatial non-stationarity was first introduced by Fotheringham, Charlton, and Brunsdon (Fotheringham et al. 1996 ). In their paper, they pointed out that even though researchers had recognized the spatial component in data, global models were still widely used in studies.
