Hi Deepa, I'm not sure if your message is an accidental duplicate of your earlier message, or an intentional resubmission of the original question. In either event, it gives me a chance to briefly chime in. As Kosuke mentioned on your first message, Average Treatment Effect (ATE) is functionality that was present in Zelig 3.5, and has not yet been included in Zelig 4. (It is possible to revert to Zelig 3.5 - send me questions or see earlier list questions on how to do this). You can see that adding ATE is an issue in the developer Zelig list on Github, and is scheduled to be included within the next three weeks.

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? 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.
