Thank you for this great work!

PS overlap weight exaggerates population in the overlap. I wonder how this affects on reliability of the method just like empirical equipose. ;) @schuemie

Should we change all 'iptw' column name in dataframes into 'weightedPs'?

@yongyonglee Please add more details. I think the issue below is generated by the same problem: https://forums.ohdsi.org/t/prediction-model-external-validation/17416/2

I prefer option 2 (adding querySql.tibble), since many OHDSI tools are based on querySql. And some old functions and '[' might not work on tibbles.
