Software
Geostatistical Analyst is an extension to ArcGIS desktop that provides tools for spatial data exploration and surface generation.
ArcGIS Geostatistical Analyst software may be found at:
http://www.esri.com/software/arcgis/extensions/geostatistical/index.html
Here you will find a short video of ArcGIS Spatial Analyst
(http://www.esri.com/software/arcgis/extensions/geostatistical/demos.html) and more additional information on the analytical functions available within this extension.
Note: Geographically Weighted Regression (GWR) was introduced with ArcGIS 9.3 and is available in the Spatial Statistics Toolbox with ArcInfo, ArcGIS Spatial Analyst, or ArcGIS Geostatistical Analyst.
