Include report for geographically weighted regression (as an explanatory tool)
A good idea might be the creation of report for geographically weighted regression (GWR) model. It is a widely used local regression analysis (mostly utilized as an explanatory tool but it can be used for other purposes like disaggregation of spatial data). Also, as an extra feature, a good idea would be to include if someone used fixed or adaptive kernel bandwidth.
How could we do it?
Yes. This example can be found here. They are using a fixed kernel size and they apply GWR to a raster dataset.
library(gstat)
library(spgwr)
data(meuse)
coordinates(meuse) <- c("x", "y")
meuse$ffreq <- factor(meuse$ffreq)
data(meuse.grid)
coordinates(meuse.grid) <- c("x", "y")
meuse.grid$ffreq <- factor(meuse.grid$ffreq)
gridded(meuse.grid) <- TRUE
spplot(meuse.grid, "soil", col.regions=topo.colors)
xx <- gwr(cadmium ~ dist, meuse, bandwidth = 228, hatmatrix=TRUE)
xx
x <- gwr(cadmium ~ dist, meuse, bandwidth = 228, fit.points = meuse.grid, predict=TRUE, se.fit=TRUE, fittedGWRobject=xx)
x
spplot(x$SDF, "pred", col.regions= terrain.colors )
spplot(x$SDF, "pred.se",col.regions=rainbow)
For a more detailed example, I would recommend this article where they are using polygon symbols but they investigate both fixed and adaptive kernel, they assessing the statistical significance of their findings and they explain why they used GWR in the first place.
