Application of Weighted Semivariogram Model (WSVM) based on fitness to experimental semivariogram on estimation of rainfall amount

, 2011
Abstract. This study presents a weighted semivariogram model (WSVM) which is intended to reduce the uncertainties in the selection of the best-fit semivariogram model and associated parameters. The proposed WSVM is based on the combined forecast method, providing the weighted average semivariogram by summing up the product of estimated semivariograms ...

Production of a Porosity Map by Kriging in Sandstone Reservoirs, Case Study from the Sava Depression

Kartografija i Geoinformacije, 2008
Variogram analyses and usages of geostatistical interpolations have been standard analytical tools in Croatian geology in the last five years. Such analyses have especially been applied in the mapping of petroleum geological data.

Using Spatial Analysis to Study the Values of Variable Rate Technology and Information [PDF]

We present a review of the last few years' literature on the economic feasibility of variable rate technology in agriculture. Much of the research on this topic has involved the estimation of site-specific yield response functions.

Granger causality between energy use and economic growth in France with using geostatistical models [PDF]

This paper introduces a new way for investigating linear and nonlinear Granger causality between energy use and economic growth in France over the period 1960_2005 with using geostatistical models (kiriging and IDW).

Empirical semivariograms for kriging interpolation

, 2009
Kriging interpolation is one of the more interesting techniques introduced in the field of surrogate modeling in the last years. This technique has been motivated by the necessity of data interpolation in the geological field in the late sixties. This approach is founded on the availability of the so called "variogram", defined as "a curve representing

Spatial circular matrices, with applications [PDF]

The cumulants of the quadratic forms associated to the so-called spatial design matrices are often needed for inference in the context of isotropic processes on uniform grids.
