Hi Casey, As one example (I'm sure there are better ways), you can see how I talk about it in this paper: Stuart, E.A., and Green, K.M. (2008). Using Full Matching to Estimate Causal Effects in Non-Experimental Studies: Examining the Relationship between Adolescent Marijuana Use and Adult Outcomes. Developmental Psychology 44(2): 395-406.
