<P>看看帮助里的说明</P>
<P>The Spatial Statistics toolbox contains statistical tools for analyzing the distribution of geographic features: finding the geographic center, identifying statistically significant spatial clusters (hot spots) or outliers, assessing overall patterns of clustering or dispersion, and so on. Spatial statistics differ from traditional statistics in that space and spatial relationships are an integral and implicit component of analysis. These tools demonstrate a variety of statistical operations appropriate for analyzing geographic data. In addition, the source code (Python and Visual Basic) for all the tools in the Spatial Statistics toolbox is provided to encourage you to learn from, modify, extend and share these and other analysis tools. For more information about these tools and statistical analysis of geographic data in general, see The ESRI Guide to GIS Analysis,Volumes 1 and 2 (Volume 2 discusses the methods in the Spatial Statistics toolbox, publication; 2004). </P>

<p>The following toolsets are provided with the Spatial Statistics toolbox at ArcGIS 9.
<p>
<p><BR>Toolset Description Analyzing Patterns These tools evaluate if features or attribute values form a clustered, uniform, or random pattern across the region. Mapping Clusters These tools may be used to identify statistically significant hot spots, cold spots, or spatial outliers. Measuring Geographic Distributions These tools address questions such as: Where's the center? What's the shape and orientation? How dispersed are the features? Utilities These tools may be used to reformat data or to render analysis results.
