Dear all,
I have a question about using Zelig on matched data. I have a matched
dataset in Stata format (I used genetic matching with MatchIt), and I'd like
to analyze it with Zelig. Can I simply load that dataset into R and run
Zelig?
Thank you,
Ana

Dear Ana,
If you used genetic matching with MatchIt, your code should have
returned R data sets. If you have imported these data sets into Stata
format, you can import them into R using the foreign library read.dta
(see http://www.ats.ucla.edu/stat/r/faq/inputdata_R.htm). However, it
is probably better to use the original datasets from MatchIt as the
exporting and re-importing creates information loss. See demo(match)
in Zelig for an example for how to call matchit then zelig.
Best,
Olivia

From the perspective that matching is a nonparametric
preprocessing (see
Ho et al. Political Analysis paper), you can just apply standard
regression models in the matched data set.
Good luck,
