Comparison of kriging with external drift and regression - kriging ∗ July 3 , 2003

A. 2003. Comparison of krig-ing with external drift and regression-kriging. A generic framework for spatial prediction of soil variables based on regression-kriging. In further text, theory behind kriging with external drift and regression-kriging and differences between them are explained in more detail. We focus mainly on practical issues, i.e. how to derive predictions and prediction uncertainty. We also give a small case study where you can follow calculation of different elements. Use footnotes to obtain additional explanations. For an introduction to matrix algebra, read the general introductions in classical statistical books (Neter et al., 1996, §5). A detailed introduction to matrix algebra for KED can be found in Wackernagel (1998, appendix).
