GpVariogram Gaussian Process Variogram
=GpVariogram(Variogram, h, RangeOrBeta, SillOrAlpha, Nugget)
Parameters
Variogram: (see Variograms section for details)
- 3 = Exponential
- 5 = Spherical
- 9 = Gaussian
- 10 = Power
h: Lag distance
RangeOrBeta: Distance in which the difference of the variogram from the sill becomes negligible (Range) or exponent of the power variogram (β)
SillOrAlpha: Limit of the variogram tending to infinity lag distances (Sill) or power variogram constant (α)
Nugget: [Optional] Height of the jump of the variogram at the discontinuity at the origin (default = 0)
Variograms
GpVariogram return the value of the selected variogram. The variogram represent function dependance on parameters. Four variograms are available.
