  • Kriging

    In statistics, originally in geostatistics, kriging or Gaussian regression is a method of interpolation for which the interpolated values are modeled by a Gaussian governed by prior covariances.Under suitable assumptions on the priors, kriging gives the best linear unbiased prediction of the intermediate values. [citation needed] Interpolating methods based on other criteria
