Hi,
I am doing a fixed effects regression and I am a bit worried, that I should include year dummies, which I am currently not.
I did use the forum search, but I did not find a satisfying answer...
So - first I do:
resulting in:
Does that mean: We reject the null that the coefficients for all years are jointly equal to zero, therefore time fixedeffects are needed in this case.
And if I need time effects - is that simply done by including i.Year dummies?

Code:
xtreg $ylist $xlist i.Year, fe testparm i.Year
Code:
( 1) 2005.Year = 0
( 2) 2006.Year = 0
( 3) 2007.Year = 0
( 4) 2008.Year = 0
( 5) 2009.Year = 0
( 6) 2010.Year = 0
( 7) 2011.Year = 0
( 8) 2012.Year = 0
( 9) 2013.Year = 0
F( 9, 143) = 47.31
Prob > F = 0.0000
