Bayesian Nonparametric Kriging

Statistical spatial analysis methods are evolving at a rapid rate as a result of increased active basic research and new journals promoting such methods in applied settings. One such journal is the Journal of Agricultural, Biological, and Environmental Statistics. An article by authors Woodard, Wolpert and O’Connel, Spatial Inference of Nitrate Concentrations in Groundwater, June 2010, illustrates nicely the application of nonparametric bayesian kriging via a spatial moving average model. This approach improves upon traditional kriging methods in many ways. The authors provide an S-Plus software package, spatialLrf, to implement the new algorithm.
