You will increase your change to get an answer by (1) using a more informative subject (2) reading some statistical manuals and then re-posting a question that sounds more Stata-related than merely statistical.
If I were you, my strategy would be:
(1) using -xtreg- followed by -xttest0-
(2) if the test is NOT significant, then use -regress-
(3) if the test is significant, then (a) use -xtoverid- (you can download it by typing ssc install xtoverid), and (b) if this test is significant, then turn to -xtreg, fe-
Obviously, you may have heteroskedasticity and autocrrelation problems, but this is another story.
