Dear All
Has anyone implemented a spatially dependent regression analysis?
r.regression.line is not spatial
I want to fit a high resolution photogrammetrically derived surface model to which is tilted, to a coarser DEM (SRTM) and need to calculate the polynomial coefficiants via a regression to transform the one to the other.
Greetings Wolfgang
I think what you are looking for is Geographically Weighted Regression
(GWR) it's been implemented in R and there is a GRASS + R interface.
