Trying - unsuccessfully- to run some clustering and autocorrelation analysis in 9.2

Good afternoon,

For my masters dissertation I'm looking at the socioeconomic impact of Edinburgh's historic trolley system. I'd like to do something with spatial autocorrelation and clustering along the network but have been all but completely unsuccessful.

I've managed to get the 'Cluster and Outlier Analysis (Anselin Local Moran's I)' tool to run twice in 3 days, and only once correctly.

I made a test file of points, coded them with rents and deliberately clustered or scattered them. I ran it with inverse distance and the one time it worked and gave me sensible answers. I haven't been able to get the program to run with the same settings again.

The process has also run once using a weights file that I created, using the methodology outlined here: <http://webhelp.esri.com/arcgisdesktop/9.2/index.cfm?TopicName=Modeling%20spatial%20relationships>.  The answers it gave me made no sense, however, with the LMicluster field showing very negative values (e.g. -84.3873846) for my clustered points and very positive value for my scattered points. I haven't been able to get the tool to run again.


I keep getting a popup that tells me that python.exe has encountered a problem and needs to close. When I searched for the specific error message online, I came upon this forum thread <http://forums.esri.com/Thread.asp?c=93&f=983&t=248033
>, but I know the department has the right version of Python for 9.2.

I'm out of ideas and so is the IT staff here. Can you help, or know where else to look?

Thanks,
Angela
