If you think it is appropriate to do so, you can recover beta coefficients
manually yourself. As far as I can tell, that is pretty much what -betacoef-
does internally.

Subject: st: Calculate beta values for mim results
Dear All,
Can I calculate beta values besides the standard estimates that the - mim-
command produces? I tried using the below commands, but results returned
no values. Thank you.
Best regards,
Frank
mim: regress y x1 x2.....
mim, storebv
betacoef
return list
matrix list r(beta)
Results:
r(beta) [1,23]
x1 x2... _cons
