Is there any package for stacked event-by-event estimates ?

[Phuc Nguyen]

I am reading a paper of Cengiz, 2019 about using stacked event-by-event estimates for the Difference-in-Differences settings. This is a good estimator for examining the effect of law without any control unit.I am wondering if Stata has any package for this estimator.

Many thanks and warm regards.

hello,

Firstly, this paper had posted its replication code online.

Secondly, csdid seems to provide an option("reg") for stacked did.
