Thank you so much for building this package. I was wondering if there is a way to test the equality of estimated coefficients across different ATTs across groups? For example, we can get average effect by group using ggdid(agg.gs), but is there a way in the package to test whether these coefficients are statistically equal to each other or not?
Appreciate your attention to this question in advance.
