Subject: st: examples propensity score matching
Dear Stata users,
A very basic question. I want to take a look at how to do a propensity
score matching in stata (commands psmatch2, pscore, I think).
I have two cross sectional surveys (t1, t2) where I observe treatment and
control individuals in the second period but I cant know the conterfactual
in t1. I want to use propensity score matching to indivudals in t2 to
individuals in t1 based on some observable characteristics.
I have technical readings and literature but I would like to know the how
to in Stata. how the data should look? should I pool individuals for both
cross-sections?
thanks,
Gaby
