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 diagnostics.
Thanks for your thoughts.

please note that the answer I received was incorrect as was carefully pointed out by a rather irate reviewer.
