Connections between the methods are discussed and implementation of the models using S-PLUS is described.
WebSeveral packages are available in R to conduct interpolation by kriging, including “kriging” (simple package covering ordinary kriging), “gstat” (enables many forms of kriging … WebThe thin-plate splines have an important advantage with regard to universal kriging because they do not need to fit variograms. Moreover, the estimators of the thin-plane splines can be obtained in a closed form by solving a linear system of n equations, where n is the number of data points.
