No, it is not hell! Collinearity between the independent vars and the panel
identifier prevents Stata from estimating your model. This would be the
reaction of every other software as well, I guess.
Find out which variable is causing the problem! To this end, type
*************
xtset
corr `r(panelvar)' x*
*************
where "x*" should be replaced with your independent variables that you had
fed to -xtreg- when the problem occurred. Any correlation off the main
diagonal should be examined whether it approaches 1 or -1.

Betreff: st: unbalanced panel
Dear users!
Having destringed and sorted my data, I tried the xtreg command for my
unbalanced panel!
But... "independent variables are collinear with the panel variable"
What should I do???
...Stata seems a hell for me!!!
