Geostatistical Estimation Methods: Kriging SpringerLink

Kriging predicts the value of a function at a given point by computing a weighted average of the known values of the function in the neighborhood of the point. The method is closely related to regression analysis. Both theories derive a best linear unbiased estimator based on assumptions on covariances, make use of Gauss–Markov theorem to prove independence of the estimate and error, and use very similar formulae. Even so, they are useful in different frameworks: kriging is … WebJul 16, 2024 · This chapter presents geostatistical estimation methods for modeling continuous variables.
