To estimate event-study/dynamic effects, we strongly recommend using the much faster did_multiplegt_dyn command, available from the CRAN repository. In addition to that, did_multiplegt_dyn offers more options than did_multiplegt.
Warning message:
There was 1 warning in `summarize()`.
ℹ In argument: `Tgroup = group_indices()`.
ℹ In group 1: `T = 1980`.
Caused by warning:
! `group_indices()` was deprecated in dplyr 1.0.0.
ℹ Please use `cur_group_id()` instead.
ℹ The deprecated feature was likely used in the DIDmultiplegt package.
  Please report the issue to the authors.
