Overview
The Model program constructs a 2D nested model with the help of experimental (cross) variogram(s) produced by Vario2D with PCF [45]. It deals with 2D anisotropic modeling of one or two variables but does not provide any facility for constructing a global coherent model of coregionalization.
Directional variograms are read from a variogram file [6.5]. Scroll bars can change the parameters of the 2D nested model. Each time a parameter is modified, cross sections through the 2D model are redrawn along with the directional variogram(s) used to fit the model.
A 2D nested model can be fitted against any of the measures of spatial continuity available in Vario2D with PCF [4.7].
An indicative goodness of fit (IGF) is computed every time the model changes. The best IGF is stored in memory and can be recalled at any time. A user’s model can also be stored in memory.
The 2D nested model of spatial continuity can be saved as a grid file [6.3]. This file can then be used to produce a variogram surface representation of the 2D nested model.
