Hello all, I'm a bit of a rookie with GeoStatistics. I am interested in Kriging with External Drift but I am having a hard time finding information that tells you how it works in laymans terms (without just firing a matrix at you and leaving you to deduce what it means).
I don't think this is right but I'll give it a shot. Does it work as follows : 1) Compute a trend for the drift variable 2) Remove the trend computed in 1) from the main variable 3) Grid the residuals from step 2) 4) Add back the trend from step 1) I don't think this is right but if you can explain to me how the Drift is actually applied in laymans terms it would be greatly appreciated. Also when you do kriging with external drift do you have to model a variogram or can a reasonable one be computed automatically, if so how would you compute it? Also if you have any good sources of information on Kriging with external drift could you pass them on to me?
