st: Betas from repeated tobit estimations

[Paulo Peneda Saraiva <Paulo.Peneda_Saraiva@nottingham.ac.uk>]

Dear all,

I have a quick question. I want to have access of different betas that I get from running a two limit Tobit estimation in different groups. I have different "Subjects"  and for each of these "Subjects" I estimate the two limit tobit using a dep. variable (Cx), one independent variable (M) and robust s.e.

After this, I want to have access to the list of estimated betas. I have tried two approaches:

"by Subject, sort: tobit Cx M, noconstant ll(0) ul(3) vce(robust)"
With this, I can not find the betas per "Subject". The e() or r() just gives me last estimation.

OR

"byvar Subject, e(rmse) b(M): tobit Cx M, ll(0) ul(3) nocons"
This saves the betas, but does not let me use the vce option:


Anyone can help me out?

Many thanks in advance.
