st: Sargan test

[Pedro Juan Garc�a Teruel <pjteruel@um.es>]

Hi,
I am using the command xtabond with endogenous variables, and in
differents estimations always I have got a P value=1.00 in Sargan Test.
What is the meaning of this value equal to 1?
Could be able to have a econometric problem which make the P value was
always 1.00?
Thanks,
