Figure 2From: Comparison of tests for spatial heterogeneity on data with global clustering patterns and outliersLocal cluster. Graphical representation of the simulated relative risk for each of the three alternative data set with local clustering. The relative risk for the counties of Manassas City Virginia (2 adjacent neighbors), Jackson County Kansas (6 adjacent neighbors), and Fulton County Georgia (10 adjacent neighbors) are set to 4. All other counties in the United States (excluding Alaska and Hawaii) are set to 1.Back to article page
