The available variogram models are as follows. Each is a family of functions of , the distance, with parameters , , and corresponding to the nugget, sill, and range, respectively. After defining each variogram model, you see a graph of the variogram with parameters , , and , displayed for from 0 to 6. Dashed lines indicate the nugget, sill, and range, and a gray rectangle indicates the bounds between which the variogram is guaranteed to lie at distances greater than the range. After this graph, you see a heat map of a sample generated with GenerateSpatialData according to the same variogram over a square with sides of length 6.

Setting the variogram explicitly is not required, as a variogram with estimated parameters is set by default. However, it leads to better results if the correct variogram is set.
