ArcGIS Geostatistical Analyst is an extension to ArcGIS Desktop (ArcInfo, ArcEditor, and ArcView) that provides a variety of tools for spatial data exploration, identification of data anomalies, optimum prediction, evaluation of prediction uncertainty, and surface creation. With ArcGIS Geostatistical Analyst you can:

• Explore data variability, look for data outliers, examine global trends, and investigate spatial autocorrelation and the correlation between multiple data sets.
• Create prediction, prediction standard errors, the probability that specified threshold was exceeded, and quantile maps using various geostatistical models and tools.

ArcGIS Geostatistical Analyst is a complete package for spatial data preprocessing, geostatistical analysis, contouring, and post-processing. It also includes interactive graphical tools with robust parameters for default models to help newcomers to geostatistical data analysis. Geostatistical Analyst leverages ArcGIS data management, visualization, and mapping tools to put powerful geostatistical analysis tools in the hands of GIS users.
