Dear all,

I am trying to figure out how after a regression, I can save the coefficient estimates and p-values, and use some of the coefficients (only the coeff starting by "extra") for a kernel density graph.
I have tried estimates save command, but the file is a .ster format and not .dta, so I don't know if it is useful for my purpose.

Here's my example:
Code:
unab PTA : PTA*
unab extra : extra*
reghdfe ln_imports `PTA' `extra' ,vce(cluster pair) absorb(i.imp#i.year i.exp#i.year pair)
estimates save coeffextra249
kdensity extra*, norm
Best regards
