Sas/Stat Technical Report: Spatial Prediction Using the Sas System
Sas/Stat Technical Report Spatial Prediction Using the Sas System Author:Sas Spatial prediction using ordinary kriging involves two steps: modeling the covariance or semivariogram of the spatial process and then using this model in solving the kriging system at a specified set of spatial points. This report documents two SAS/STAT procedures used for spatial prediction for two-dimensional data: PROC VARIOGRAM (models spat... more »ial dependence) and PROC KRIGE2D (performs ordinary kriging). An example of spatial prediction demonstrates both procedures and gives details of variogram estimation and ordinary kriging.« less
