Hi! I wonder that can we conduct IPTW in CohortMethod instead ps matching? For instance, let’s say I want to make a characteristic table Before weighting and After weighting. Is this possible in here? Thank you! 
IPTWis fully supported in the upcoming CohortMethod 5.0.0 release. It is ready in the develop branch, I’m just waiting for the Shiny app to be finished. V5.0.0 introduces quite a lot of changes throughout CohortMethod, so may not be worth the effort.
In general I recommend against using IPTW. We’ve found it to produce biased estimates compared to PS matching or stratification, as for example demonstrated here. I know IPTW is the fashionable thing to do, but be sure to include plenty of negative controls to verify it doesn’t mislead you.
Oh I see. Well then I can’t wait to release CohortMethod 5.0.0!
Thank you for everything
