csdid stata

[Oussama Ben Atta]

I have a question about the results below, which I obtained after running the csdid command with the method(dripw) option. I interpret the result as indicating that the coefficient of the pre-treatment mean is significant, but the parallel trend seems to be respected insofar as the pre-treatment coefficients are stable. Therefore, we can say that there is an effect after treatment. What do you think about this interpretation? Is it correct?

Thank you in advance for your feedback.

This is a pretty clear violation of parallel trends. The blue dots measure the difference in trends (from period to period) between the treated cohorts and the never treated cohort (if you used all of the defaults). Incidentally, I would use the "long2" option because this gives the much more standard event study plot.

Please follow the guidelines and show use the Stata command you typed, as I can't even tell if this is a staggered intervention, and I don't know which options you used.
