FSA Reduced Configurations for Highly Risky Emissions

Optimal Solution	Coverage	Consistency
AF-AMER*LOWINC	.331	.953
AF-AMER*LATINO	.191	.953
AF-AMERSIZEBRANCH	.181	.936
LATINOLOWINCBRANCH	.138	.976
Solution Coverage: .431
Solution Consistency: .925

Note: AF-AMER = African American population; BRANCH = branch plant; LATINO = Latino population; LOWINC = low income; SIZE = facility size; and SUBSID = subsidiary. Consistency is a measure of how often the solution is a subset of the outcome or the degree to which cases sharing a particular combination of conditions agree in displaying the outcome in question. Coverage measures how much of the outcome is explained by the solution or the empirical relevance of a particular combination of conditions.
