How to get constant term in -csdid- ?

[Parul Gupta]

I am using -csdid- and need to see the constant term in the results table to interpret the output. Is this possible? My code is given below.

 csdid `outcome' `covariates', time(year) gvar(gvar) cluster(regionID)
            
           scalar ss = e(N)
            estat simple, estore(`est_name')
            estat pretrend
            cap scalar pval = r(pchi2)

There is no Constant
CSDID basically gives you the difference (adjusted) between observed and potential outcomes
F

I see.
What if I want to say something like "The average difference pre-intervention was X units , and now is it lower by Y units"? Can I show X in the table, so that the comparison is meaningful with respect to a baseline?

Ahh, Unfortunately no. CSDID was not written with that in mind ( the outcome is never estimated)

you would need use a different estimator perhaps.

Thanks for clarifying.

Last question:
Suppose I want to show the control group's mean post-treatment (Z). So, that I can say "Without the treatment, the treated group's average outcome would have been Z, but now it is lower/higher by Y".
If we use -estat event-, the first two lines in the output table give "pre-average" and "post-average". Can these be used in any way to (manually) get my intended estimate? Or any other command that I could use?

Thanks for all your help!
