What is the ArcGIS Geostatistical Analyst extension?

The ArcGIS Geostatistical Analyst extension provides the capability for surface modeling using deterministic and geostatistical methods. The tools it provides are fully integrated with the GIS modeling environments and allow GIS professionals to generate interpolation models and assess their quality before using them in any further analysis. Surfaces (model output) can subsequently be used in models (both in the ModelBuilder and Python environments), visualized, and analyzed using other ArcGIS extensions, such as ArcGIS Spatial Analyst extension and ArcGIS 3D Analyst extension.

The tools provided in the ArcGIS Geostatistical Analyst extension are grouped into three categories:
