FAQ: How does the search neighborhood influence a Geostatistical prediction?

Question

How does the search neighborhood influence a Geostatistical prediction?

Answer

The value at an unknown location is predicted using only those data points located within the search neighborhood when it has been defined. Point locations are only assumed for those points within the defined search neighborhood. When using a small neighborhood, a trend component in the data can be ignored. As a guide, select the number of neighbors on the basis that few will have a prediction weight of less than 1%.
