WebNov 1, 2024 · The GWR and MGWR improve the fit as expected (GWR: adjusted R 2 = 0.818; MGWR: adjusted R 2 = 0.831) over the MLR (adjusted R 2 = 0.710). However, it would be unwise to compare the three models by their adjusted R 2 only. Cross-model fits can be compared more effectively using specific information criteria such as the AICc, … WebAlso shown are the GWR parameter estimates, expressed as a range of values that have been computed. In the diagnostics section of this table note the drop in residual sum of squares, the increase in the adjusted R 2, and a modest fall in the AICc statistic. The authors suggest that a fall of 3 or more in the AICc value warrants examination as ...
Web3.1 Model Selection. We use the gwr.model.selection() function to go through models with different permutations of the independent variables. This returns an object with the model, the independent variables and the kernel, AIC, AICc, and RSS of the models. As we will be doing this for the 4 different permutations, we create functions to run the model selection, …
