st: "insufficient observations" with xtreg
Dear all,
I have some problems with my panel dataset. I first ran:
. tsset var67 year
panel variable: var67, 1 to 2662
time variable: year, 1994 to 2004
Then I used xtreg, but got the error message about insufficient
observation (2001).
I'd really appreciate it if someone can help me with it.
