Hi,

I'm using xtabond2 with stata/se 8.0 (68 countries between 1960 and 2006).
However, I'm having troubles with the memory

no room to add more variables due to width

What did I do? Without success, I tried to compress, to drop variables not
regressed, to enlarge the memory, maxvar and matsize.

With a relative success, I used the if-command and I estimated some GMM 2st=
ep
robust using only 10 consecutive years and the 68 countries. However, somet=
imes
I need to make the periods even smaller (4 years, for instance), which I do=
  not
desire.

How can I solve the problem and at least get results for n=3D68 and t=3D20?

Yours, Paulo.
