Limiting Distribution of Variogram Estimator

open access: yes, 2008
The paper deals with the problem of a statistical analysis of time series connected with the estimation of variogram. The limiting expressions of the first two moments and the higher order cumulants of the classical variogram estimator of Gaussian ...

Web-based tool for expert elicitation of the variogram

open access: yes, 2013
The variogram is the keystone of geostatistics. Estimation of the variogram is deficient and difficult when there are no or too few observations available due to budget constraints or physical and temporal obstacles.

Highly Robust Variogram Estimation

open access: yes
In the context of spatial statistics, the classical variogram estimator proposed by Matheron is not robust against outliers in the data, nor is Cressie and Hawkins' estimator.

Bayesian Variogram Modeling for an Isotropic Spatial Process

open access: yes, 1997
The variogram is a basic tool in geostatistics. In the case of an assumed isotropic process, it is used to compare variability of the difference between pairs of observations as a function of their distance.

VARIOG2D: a computer program for estimating the semi-variogram and its uncertainty

open access: yes, 2001
Copyright © 2001 Published by Elsevier ScienceVARIOG2D is a Fortran-77 program that provides four basic operations for semi-variogram analysis: inference of the experimental semi-variogram, estimation of the variance–covariance matrix of the experimental

The mutual variogram estimate of the signal processes

open access: yes, 2003
The paper deals with the problem of a statistical analysis of time series connected with the estimation of mutual variogram, a measure of spatial correlation. G. Matheron has coined the term variogram, although earlier appearances of this function can be

Reducing fluctuations in the sample variogram

open access: yes, 2007
Publicación ISIIn the analysis of regionalized data, irregular sampling patterns are often responsible for large deviations (fluctuations) between the theoretical and sample semi-variograms.

Benchmarking Knowledge-assisted Kriging for Automated Spatial Interpolation of Wind Measurements

open access: yes
- We have benchmarked a novel knowledge-assisted kriging algorithm that allows regions of spatial cohesion to be specified and variograms calculated for each region.
