st: Spatial weight matrix: r(198)

[Natalie Trapp <natalie.trapp@zmaw.de>]

Dear all,

I am using Stata 11 and would like to do a test on spatial 
autocorrelation. Unfortunately I had problems with setting matsize, as 
my data set is too huge (>44.000 obs.). I therefore deleted all the 
observations that were under a certain monetary value and then could set 
matsize to 6500. While I was creating the spatial matrix I got the error 
"obs must be between 4126 and 334910". However, I do have 4126 
observations left after the deletion of more than 40.000 observations.

Could someone tell me what this error message exactly means or what 
mistake I did?
Thank you very much in advance!
