Hi, I am trying to estimate average treatment effect on treated using the steps in Ho, Imai, Kin and Stuart, 2011 paper. But I am getting warning message that cond is not supported by this version of zelig. I also tried the earlier version of zelig, but unfortunatley it also gives same warning. However, I can still get some results despite of the warning message when I continue with the following step given in the paper. So does the warning sign cause significant effect on the result? Or is there any other way to change the command line and get the required result? Warning message: In setx.default(z.out1, data = match.data(m.out, "treat"), cond = TRUE) : "cond" is not currently supported by this version of Zelig Any help will be much appreciated. Thanks a lot.
