Hi Agustin,

You should be able to get which observations were matched through the "cem_matched" variable that is added to the data after running cem. Also take a look at the "cem_strata" variable. Observations in the same strata are matched to each other.

Hope that helps!

Cheers,

Matt

Hello,

I am running the following command on cem:

cem var1 var2 var3, tr(tr_var) k2k

I get the output:

Matching Summary:
-----------------
Number of strata: 19
Number of matched strata: 8

                        0             1
All                 2327       190
Matched       171          171
Unmatched 2156      19

Now I need to get the list of all the 171 matches. I need to know exactly which 171 treated samples where matched to which 171 control samples, so that I can obtain experimental (output) data only from those, and not the whole 2327 + 190 dataset.
I assume this data is stored in r(match_table), but I do not know how to retrieve it.

Thanks in advance!
