Geostatistics

Geostatistics is a branch of statistics focusing on spatiotemporal datasets.

Geostatistics evolved in mineral exploration and mining of minerals, ores, and coals.

Geostatistics are statistical methods to describe spatial relationships among sample data and to apply this analysis to the prediction of spatial and temporal phenomena.

Geostatistics
Geostatistics is an application of the theory of random functions for estimating natural phenomena. It was traditionally used in geo-sciences.

Geostatistics
Main article: Geostatistics
Geostatistics is a point-pattern analysis that produces field predictions from data points. It is a way of looking at the statistical properties of those special data.

idw is a surface generation utility which uses inverse distance squared weighting (as described in Applied Geostatistics by E. H. Isaaks and R. M. Srivastava, Oxford University Press, 1989) to assign interpolated values.

[spatial statistics (use for geostatistics)] An interpolation technique in which the surrounding measured values are weighted to derive a predicted value for an unmeasured location.

Making Effective Use of Geostatistics
Geostatistical analysis enables you to study geographic distribution of regionalized variables, applying statistical methods to spatial interpolation.
