For Carlos (I have edited it a bit, hope correctly. m.p.):

I cannot post to statalist. Could you send to list, it is urgente.É
desenvolimento for my dissertation.

I try to determine the propensity score does the following error:

The treatment is id

          ID | Freq. Percent Cum.
------------ + ------------------------------****-----

      310,100 | 41 46.07 46.07
      313,810 | 48 53.93 100.00
------------ + ------------------------------****-----

       Total | 89 100.00

Estimation of the propensity score

outcome does not vary, remember:
                                   0 = negative outcome,
         All Other nonmissing values = positive outcome
r (2000);

I use the following algorithmic:
