Hi all, I?m a bit confused on what we should use as the data and what we should use as the counterfactual in problem 3.1. This is what I have: data = biochem Then for the counterfactual. I have the two individuals from 2.4 define as: single.subject <- c("art"=mean(Exp.Y.single), "kid5"=median(bioChemists$kid5), "phd"=median(bioChemists$phd), "ment"=median(bioChemists$ment), "fem.binary"=median(bioChemists$fem.binary), "mar.binary"=0) married.subject <- c("art"=mean(Exp.Y.married), "kid5"=median(bioChemists$kid5), "phd"=median(bioChemists$phd), "ment"=median(bioChemists$ment), "fem.binary"=median(bioChemists$fem.binary), "mar.binary"=1) then I rbind these two observations to be the counterfactual. Could someone let me know if I?m on the right path?
