WebKriging is a method of data interpolation based on predefined covariance models. The aim of kriging is to derive the value of a field at some point , when there are fixed observed values at given points . The resluting value at is calculated as a weighted mean: The weights depent on the given covariance model and the location of the target ... WebCokriging uses two or more (up to four) datasets to refine the predicted values. It does require a model of the spatial correlation for each variable and for the spatial correlation between all pairs of variables. thz in 1/s

WebCokriging uses information on several variable types. The main variable of interest is Z 1, and both autocorrelation for Z 1 and cross-correlations between Z 1 and all other variable types are used to make better predictions. It is appealing to use information from other variables to help make predictions, but it comes at a price. Web1.2 R and gstat R is set up as a base system with many contributed libraries, among which are several for geostatistics, including spatial[17], geoR[13], and gstat[12].
