Kriging

Kriging is a geostatistical technique for spatio-temporal interpolation used in a variety of disciplines such geology and meteorology. It allows you to estimate unknown values at specific locations given the available values at other locations.

The Kriging function implemented in XLSTAT-R allows you to create gstat objects, generate a variogram model and fit a Variogram model to a sample Variogram. Three types of kriging can be applied: the ordinary, the simple and the universal kriging. This XLSTAT-R function calls the gstat, vgm and fit.variogram functions from the gstat package in R (Edzer Pebesma, Benedikt Graeler).
