Hello everybody, this is my first topic here, i am brazilian so sorry for my english....

Well, i am trying to run a panel data model, when I estimate the model, it simply does not show numerical results, only dots appear in the stata regression. I am not finding anywhere an
explanation for what is happening, could anyone help me? I will put the regression downhere.

I Uploaded 2 attachments, the first one is an excel table, showing the panel used in the stata.
The second attachment is a 'stata archieve' called "Rotina", is the routine of my regressions to you all look.
