Modelling a semi-variogram

The output of Spatial correlation and Cross Variogram result in a experimental semi-variogram. You can show the experimental semi-variogram values in a graph window. For these values, you need determine the 'best' semi-variogram model before a Kriging operation can be performed. The following semi-variogram models are available:

where:

h

is the distance

C0

is the nugget, parameter supplied by the user

C0 + C

is the sill, parameter supplied by the user

a

is the range, parameter supplied by the user

k

linear slope for the power function

m

power exponent (0 < m < 2)
