Recall that the goal of this example is spatial prediction. In particular, you would like to produce a contour map or surface plot on a regular grid of predicted values based on ordinary kriging.

High-precision geomagnetic maps are essential for geomagnetic-assisted navigation, yet their construction is constrained by kriging interpolation’s reliance on accurately modeled semi-variogram.

The OUTVAR= data set contains the standard and robust versions of the sample semivariogram, the covariance, and other information at each lag class. The details of the computation of the variogram, ...

Spatial autocorrelation in the residuals of spatial environmental models can be due to missing covariate information. In many cases, this spatial autocorrelation can be accounted for by using ...
