Hi.  I am using ArcGIS 9.3 and when I open the Arc Toolbox, the 'Modeling Spatial Relationships' tab of the Spatial Statistics Tools folder is missing the OLS Regression tool.  These are the options that it includes: Generate Network Spatial Weights; Generate Spatial Weights Matrix; Geographically Weighted Regression.  Is there a way for me to download only the OLS Regression tool or even the entire Spatial Statistics Tool Package?  Thank you in advance for any help.
