The mathematical definition of the variogram is (3.1) where Z(x,y) is the value of the variable of interest at location (x, y), and e [ ] is the statistical expectation operator.

For each of these pairs we can calculate the associated separation vector: (Dx i,j, Dy i,j) = (x i-x j, y i-y j) (3.2) When we want to infer the variogram for a particular separation vector, (x, DDy), we will use all of
