Dear Statalist members,
I am using Driscoll and Kraay standard errors with fixed effects
(within) regression (xtscc, fe)
I have a time invariant variable which is excluded when doing the
fixed effect standard model (xtreg,fe).
However this variable remains when using xtscc, fe.
Can you tell me how come my variable which is excluded in the FE model
because it does not vary within geographical area, shows up in the D-K
FE model?
Thank you,
E.L
