Figure 15. Examples of multiple indicator semivariograms at selected thresholds for layer A, showing the nature of the autocorrelation structure and the progressive change in nuggets, sills, and ranges as thresholds increase. Note that the horizontal axes for the 1- and 3-percent thresholds are 10 times smaller than for larger thresholds.
