We performed the hot spot analysis using ArcMap\u2019s Hot Spot (Getis-Ord Gi*) spatial analyst tool on the five-year lung cancer mortality rate (1999-2003) (the dependent variable), and six other explanatory variables. These explanatory variables were selected based on existing research, suggesting they are linked to lung cancer in a causal or associative manner.
