logo  GpStatsNd ND Gaussian Process Statistics

=GpStatsNd(NbClass, Scaling, xValues, fValues)


NbClass: Number of classes

Scaling: Scaling of parameters

xValues: Function parameters values

fValues: Function values


GpStatsNd must be entered as an array formula. Select a range of NbClass + 1 lines by 6 columns starting with the GpStatsNd cell. Press F2 to start edit mode and press CTRL+SHIFT+ENTER to insert the function. If the formula is not entered as an array formula, the single result is 1 (Class). The results are arranged as shown below.

Class h

The empirical variogram is calculated for each class k with the formula below where Nk is the number of points of the class k.
