Option for choosing a control group #24

Closed yujunghwang closed 1 month ago

yujunghwang commented 2 months ago

Question: is there an option for did_multiplegt_dyn to use only never treated as control, like Callaway and Sant'Anna or Sun and Abraham ?? I looked up the help file and my understanding is no. Am I correct? Thx for preparing these awesome packages !

Hi Yujung, Thanks for your interest in did_multiplegt_dyn! We have just introduced a new option ("only_never_switchers") to perform switchers vs never_switchers comparisons. You can check it out by simply updating your version of the package:

Stata: ssc install did_multiplegt_dyn, replace R: install.packages("DIDmultiplegtDYN", force = TRUE)

Best, Diego

This is amazing! Thank you for adding this option for many researchers.

Best, Yujung
