the difference of two position z (SI)-Z (SJ) size. When Si and SJ are gradually increasing in distance, they become more and more dissimilar, and their value Z (SI)-Z (SJ) will also increase in difference. You can see this in this case, which shows the analytic diagram of a typical semivariogram.　　 Note that the variance of the difference increases with the distance, so the semivariogram can be considered a dissimilarity function. The terms that are often associated with this function are
