keep_all_untreated_subset {ptetools}R Documentation

Keep All Untreated Subset

Description

A function that takes an original data set and keeps all pre-treatment data for all groups. For group g, it also includes data for the current period.

Also, note that if tp is still a pre-treatment period for group g, then periods after tp will also be dropped for group g. This is a design choice and is useful especially for estimating placebo group-time average treatment effects in pre-treatment periods.

A main use case for this function is to compute ATT(g,t)'s using a global estimation strategy such as imputation in Gardner (2022).
