Statistical tests for geographic clustering of events (e.g., disease cases) against spatial null hypotheses, including the choice and appropriateness of null models such as population-density-based expected case distributions, Monte Carlo significance testing, and density-weighted sampling. Covers methodological critiques of specific spatial clustering analyses; not purely mathematical point-set g
