Hi,

As far as I understand, the synth (synthetic control) only can have one unit under treatment against synthetic control units.

https://web.stanford.edu/~jhain/synthpage.html

I have 33 units under staggered treatment (at different time t). If I run all of these using synth method, I will have 33 estimates of effects on each.

Will there be a way to average them or aggregate them to show that on average there is a treatment effect?

Thanks
