Hi, All,

Thank you, Nick, for your email.  I will try taking a closer look at
-spautoc- later.  I was planning on doing a Moran scatter plot and
mapping the residuals.

It seems like I might be able to use the "Lagrange Multiplier
diagnostics for spatial dependence in linear models" (lm.LMtests) in
-stdep- in R.  There is also a "Moran's I test for residual spatial
autocorrelation" (lm.morantest) in the same package.  I need to look
into these further.

How much sense does it make to look for spatial dependence in my
independent variables in addition to reporting the regular descriptive
statistics?  If it exists, does it mean anything?

Thanks,
Alllan
