Hi,
I wanted to ask about my fixed effects panel data reg model. If F-test comes like this, is it because of limited within-variation in my model.
my reg code is: xtreg depvar c.indvar#c.var1 indvar var1 controls i.year, fe cluster(code)
Code:
Fixed-effects (within) regression Number of obs = 408
Group variable: code Number of groups = 35
R-sq: Obs per group:
within = 0.8481 min = 1
between = 0.0517 avg = 11.7
overall = 0.0836 max = 27
F(33,34) = .
corr(u_i, Xb) = -0.0895 Prob > F = .
(Std. Err. adjusted for 35 clusters in code)
