I am using GeoDa's Bivariate Moran's I function to examine patterns of
collocation between two variables at the county level (call them A and
B for now).
I know that, having run the analysis I can say things like "Counties
with a high value for A tend to have neighbors with a high value of B"
What I would rather say is that "Counties with a high value of A tend
to locate in regions with a high value of B" The difference being that
the latter would seem to include the county where A is high as well as
its neighbors, while the former includes only the neighbors.
I can see my way towards changing this--simply making every county its
own neighbor in the weights matrix, but I was wondering what kind of
havoc this would play on my values for I and the rest of the
Thanks for your thoughts.

The terms neighbors in OpenGeoDa INCLUDES that specific county that is the certain of discussion. So the analysis already includes that which you are looking for :)
Hope that helps!
