specification test for panel data

[alami mohammed]

Hello community
after regressing my three models (FE,RE,Poold) I know that I have to choose between them through the specification tests: Fisher , Brausch pagan and Hausman(fe-re)
the problem is the order of priority between the tests... I have read a lot of theses but each one starts with a different test... then the result will be the adoption of model different
my question is is there a sequence of test priorities to follow

thank you very much

welcome to this forum
Usually the comparison restricts to -fe- and -re- specifications, provided that a panel-wise effect do exist (so that the pooled OLS is no more an option).
That said, you do not provide the list with what you typed and what Stata gave you back (as per FAQ): without sharing these details, even the most interested and good-willing lister cannot give you a more helpful reply.
