Export ATT result after psmatch2 command

I need to export the output from the psmatch2 community-contributed command in Stata.

For example:

 psmatch2 treatment var1, neighbor(1) out(depvar)

where treatment is a dummy variable, var1 is the regressor used to estimate the treatment probability (pscore) and depvar is the outcome variable of interest. The matching algorithm is a nearest neighbor matching.

Output:

I tried to export the results with the community-contributed command esttab:

 esttab , cells(b se t)

However, instead of the ATT, I get the difference between treated and controls before matching:

Solution

  • The following works for me:

    use http://cameron.econ.ucdavis.edu/mmabook/nswpsid.dta, clear

psmatch2 TREAT AGE, neighbor(1) out(RE78)

matrix A = ( r(att) \ r(seatt) )

esttab matrix(A)

-------------------------
                        A
                       c1
-------------------------
r1              -20276.95
r2               3224.725
