Compare betas of two different models while using asdoc and reghefe

[Kedar Kelkar]

asdoc reghdfe pm rc l.pm interaction1 l.asse ///
l.lev if dummy ==0, absorb(cc industry_year_fe) keep(rc ///
interaction1) add(Firm FE, Y, Year FE, Y, Controls, Y) ///
nest replace save($results/br.doc)

asdoc reghdfe pm rc l.pm interaction1 l.asse ///
l.lev if dummy ==1, absorb(cc industry_year_fe) keep(rc ///
interaction1) add(Firm FE, Y, Year FE, Y, Controls, Y) ///
nest replace save($results/br.doc)

I wish to compare the betas of subset of dummy==0 with dummy ==1 using a simple ttest of two groups. However I am unable to do so without using eststo. Please help

Thanks

I don't know about asdoc but with most Stata procedures you can simply interact the variables with your dummy: reghdfe y i.dummy##(c.x1 c.x2)
Then you can use test directly.
