Question 3 gets to the heart of the analysis: What is the connection between leukemia and exposure to TCE?
Now that the pattern of leukemia has been determined, we can determine whether leukemia and TCE exposure are associated. Within BoundarySeer, this can be accomplished using boundary overlap statistics (Jacquez 1995). Overlap looks at the spatial association between two sets of boundaries, or a set of boundaries and TCE locations. looks at the rate of change of the variables over space by comparing values at adjacent locations.
Steps:
Import TCE injection well locations
Evaluate the association between TCE injection wells and leukemia boundaries using overlap statistics.
