It's also possible for the random field to be "intrinsic": variograms can increase without bound. The simplest example is a random walk whose variogram is linear. 3D variography is complicated. In particular, it must be guided by theoretical and statistical understanding of the underlying phenomenon; you can't do it well by treating the numbers abstractly. Consider first getting more experience by studying textbooks and papers that give extended case studies in 2D variography. | |
