Dear Mr. Hughes,
I asked Mr. Drukker at the beginning of January when some of these
commands will be available.
He said soon, but did not say an exact time. However, I don't know about
all of them.
Regards,
Natalie

The presentations listed in previous responses to this query are
useful but they are certainly not manuals and they are far from
comprehensive.
You can find a list of SSC spatial routines and related material via
--net search spatial--. In most cases the help files provide relevant
references, but I do not think that there is anything approaching a
manual or text on how carry out spatial analysis in Stata. In part
this is because the area is still developing quite rapidly, while many
researchers have used other statistical environments for their work -
Matlab, Gauss and R are heavily favoured. You could consider using
--spwmatrix-- and --splagvar-- followed by --ivreg2-- to estimate a
variety of spatial models via GMM/IV, but there are alternative
routines available - e.g. Maurizio Pisati's routines.
Two additional remarks:
1. In most cases the routines are unable to cope with missing data,
especially unbalanced panel data. As this is a characteristic feature
of many spatial datasets, you need to think how to deal with it and
choose routines that are designed to cope with it.
2. The number of spatial units (10s, 100s, 1000s, ...) is very
important for the route that you take.
Finally, a general question for all readers. The Drukker presentation
refer to forthcoming stata user modules --gs2sls-- --spreg-- and
--spivreg--. Can anyone provide information on whether these are
actually available and, if so, how one can obtain them? There is a
completely different routine (really in testing form) from William
MacMillan at the University of Michigan under the name --spreg-- .
