Abstract
I derive two new statistics, I-pop and I-pop, that adjust Moran's I t o study clustering of disease cases in areas (for example, counties) w ith different, known population densities. A simulation of Lyme diseas e in Georgia suggests that these new statistics can be more powerful t han those currently in use. This is because they consider both spatial pattern and non-binomial variance in rates as evidence supporting dis ease clusters.
