Dear Statalist,
�
My question regards the part of the psmatch2 module aimed at obtaining bootstrap standard errors using stata 9. I have managed to get standard errors for
the ATT using bootstrap, but I have not yet been able to obtain the standard errors for the ATU and ATE
�
These are the commands I use to get the se.
bs "psmatch2 treatment2, pscore(score3) out(immigrants2) common" "r(att)", reps(100) dots
bs "psmatch2 treatment2, pscore(score3) out(immigrants2) common" "r(atu)", reps(100) dots
bs "psmatch2 treatment2, pscore(score3) out(immigrants2) common" "r(ate)", reps(100) dots
�
When I try to get the se for ATU/ATE I always get this error message: statistic r(atu) evaluated to missing in full sample.
�
I would really appreciate if you could give me any comments and/or suggestions on how to proceed.
�
Best regards
