Dear Martin,

Thank you for your immediate response. I want to save the results in a
matrix so then I can 'svmat' them and take mean and SE of my estimation.
Your mata command seems to work perfectly in creating this huge matrices but
since I'm not at all familiar with mata I have 2 additional question to you
and who else knows: 

1) If I'm able to use the 'svmat' command in matrices created in mata?
2) how can I assign r() or e() values to the rows of such matrices

To give a very naive example of what I want to estimate, consider that I'm
interested on the mean (avgbeta) and the SE (bse) of the beta coefficients
of  a simple regression ran 160000, my code would be :

matrix beta = J(160000,1,0)

forvalues i=1/160000 {

reg y x
matrix beta [`i',1] = e(b)

svmat beta
qui sum beta1
local avgbeta = r(mean)
local bse = r(sd)
