Hello,

I am new to geostatistics. I was hoping someone could answer the following
question:

When trying to do external drift kriging, I understand that you create the
variogram from the residuals. Then, my question is when you actually do the
kriging, do you interpolate the residuals and add them to an ordinary kriged
field?

Or, can one just take the variogram derived from the residuals and apply it
to the raw data when kriging.

Thank you for your time and a simple response.

Chris
