Variography

On the Stats tab, in the Variography group:

• click Variogram Map to evaluate and determine anisotropic directions on a 2D plane.

• click Variograms to create a sequence of variograms at different lag intervals from each axis.

• select Omnidirectional Variograms to:

  • Calculate and display experimental semi variograms, from data sets comprised of measurements and their positions, using simplified rules.
  • Model the experimental semi variograms to obtain values for use in 3D Block Kriging and Cross Validation.

• click H-Scattergram to model semi variograms from a file containing semi variogram data.

• click Cross Validation to compare the measured value for a point with that estimated for the same location after trends have been removed and a model fitted.
