Dear forum members

I have a question about staggered diff-in-diff and event studies. I managed to fine two commands for doing a generalisation of a diff-in-diff approach tvdiff and eventdd. What is the difference between these two commands? Are they supposed to report approx the same results? I am having problems because the results I get from both of them are very very different and I do not manage to know the difference between the two commands.

Any insight will be very helpful
Thanks!
