I'm making plots of propensity score distributions - and specifically for
the matched data. If TR is my treated subsample of the matched data, do I
want TR$propens, or TR$distance, or TR$propscore? The homework solutions
for PS7 use TR$propscore, but this doesn't come up under names(TR) for me
as an option - I used distance - but I see propens listed under names.
Can someone tell me which it is supposed to be?
