Variogram

A variogram is the graphical representation of the spatial dependence between pairs of data points, commonly used in geostatistics and spatial statistics. The term is sometimes used synonymously with semivariogram, but the latter is also used by some authors to refer to half of a variogram, and should therefore be avoided. Likewise, the term semivariance…
