However, I am not sure how to get survival outcomes using this procedure. I can find some R packages for this purpose. Could you help me figure it out using SAS? Many thanks.</P> <PRE><CODE class=" language-sas">proc causaltrt data=smokingweight method=IPWS; class Sex Race Education Exercise Activity Quit /desc; psmodel Quit = Sex Age Education Exercise Activity YearsSmoke PerDay; model Change; run;</CODE></PRE> <P>&nbsp;</P> <P>&nbsp;</P> Wed, 15 Jan 2025 03:07:41 GMT https://communities.sas.com/t5/Statistical-Procedures/How-to-calculate-the-average-treatment-effect-for-the-treated/m-p/956150#M47843 SeaMoon_168 2025-01-15T03:07:41Z https://communities.sas.com/t5/Statistical-Procedures/How-to-calculate-the-average-treatment-effect-for-the-treated/m-p/956178#M47844 <P>I did move this topic to 'Statistical Procedures' - board.</P> <P>And calling&nbsp;<a href="https://communities.sas.com/t5/user/viewprofilepage/user-id/351079">@clayt85</a>&nbsp;.</P> <P>&nbsp;</P> <P>Koen</P> Wed, 15 Jan 2025 11:28:30 GMT https://communities.sas.com/t5/Statistical-Procedures/How-to-calculate-the-average-treatment-effect-for-the-treated/m-p/956178#M47844 sbxkoenk 2025-01-15T11:28:30Z https://communities.sas.com/t5/Statistical-Procedures/How-to-calculate-the-average-treatment-effect-for-the-treated/m-p/956181#M47845 <P>Are you trying to get something like an IPT-weighted hazard ratio?</P> Wed, 15 Jan 2025 11:51:20 GMT https://communities.sas.com/t5/Statistical-Procedures/How-to-calculate-the-average-treatment-effect-for-the-treated/m-p/956181#M47845 quickbluefish 2025-01-15T11:51:20Z https://communities.sas.com/t5/Statistical-Procedures/How-to-calculate-the-average-treatment-effect-for-the-treated/m-p/956265#M47849 <P>Yes, kind of.
