Figure 7

Smoothed SMR produced by the Kafadar spatial smoother available in GeoDa. Because GeoDa does not allow for flexible classification in the same way as VIT, we chose a classification similar to the one adopted in the Figure 1. We consider the counties with top 25% high SMR (in red and dark orange) as high risk. A sparsely-populated region in red (indicates "high risk") is highlighted in the circle L. For illustration purposes, we carefully draw circles (A, C, E, F, G, and H) that approximately match the corresponding clusters in Figure 4.
