Class KrigingInterpolation1D

java.lang.Object

smile.interpolation.KrigingInterpolation1D

All Implemented Interfaces:

Interpolation

public class KrigingInterpolation1D
extends java.lang.Object
implements Interpolation

Kriging interpolation for the data points irregularly distributed in space. Kriging belongs to the family of linear least squares estimation algorithms, also known as Gauss-Markov estimation or Gaussian process regression. This class implements ordinary kriging for interpolation with power variogram.
