st: analysing matrix e(betas)

Subject   st: analysing matrix e(betas)

Hello friends,

After running a panel time series mean group regression (xtmg), I want to
be able to look at the distribution of the coefficients, as well as analyse
compositional effects on the same.

Following/adapting a discussion on the statalist from 14 Oct 2010, I tried:

ereturn list
matrix list e(betas)  [Am I right to think e(betas) in this case are the
individual group coefficients?]
matrix betas = e(betas)
local xtmgcoeff = _betas[varname]

I get as far as the last line and then get the error message:

_betas not found

Any suggestions greatly appreciated,

Jeff Powell
