Table II.

Detected clusters (1) via the simultaneous cluster detection method at α = 0.05, and (2) via the two-stage cluster detection method at α = 0.05. The response is the log cancer mortality rate and the covariate is the proportion of the population in urban areas in a county. In the two-stage cluster detection’s result, clusters Ĉ3 and Ĉ5 share one common county.
