Thanks to Kit Baum, a -spautoc- package on SSC has been
updated.
-spautoc- calculates spatial autocorrelation, specifically Moran
and Geary measures, given a spatial variable and neighbourhood
information. Optionally numeric weights may be specified
reflecting e.g. distance between locations. The package contains,
as well as the main command -spautoc-, utilities -dupneigh-,
-neigh- and -numids- to help setting up neighbourhood and
weight information in the required way.
These programs all require Stata 8.
The earlier versions for Stata 5 (!) are also included:
all such files have suffix 5 to the main part of the
filename.
If you are interested in this field, you should also look
at

(help spatcorr, spatreg, spatgsa, spatlsa if installed) . . M. Pisati
3/01 pp.21--37; STB Reprints Vol 10, pp.277--298
commands for spatial data analysis including spatial (global
or local) autocorrelation, spatial correlogram, spatial lag
and spatial error regression, and tests for spatial dependence
Oddly enough, I have not yet looked in detail at Maurizio's
programs. My programs did what I wanted them to do when I first
wrote them in 1997, and as I use them in teaching and get
occasional queries about them I decided to refresh the package.
