st: how to get hold of the observations used in xtreg, fe
Dear Statalisters,
I�m running a fixed effects regression (xtreg, fe) using an unbalanced panel
dataset.
(xtreg gwgdpvdpc ln_openquota_oecd ln_govbaladj_oecd ln_unemployment
ln_lgovinvquota outputgap l.totalpop rintratelt syr termstrade fdiin
t1100gdp t1200gdp t2000gdp t3000gdp t5000gdp if year >=1990, fe)
Stata gives me the following output:
Fixed-effects (within) regression Number of obs = 53
Group variable: coid Number of groups = 14
R-sq: within = 0.8710 Obs per group: min = 1
between = 0.0000 avg = 3.8
overall = 0.0073 max = 8
F(15,24) = 10.80
corr(u_i, Xb) = -0.9992 Prob > F = 0.0000
I would like to get hold of the 53 observations stata uses for the
regression.
But when I type
list if e(sample)
Stata gives me back a lot more observations than just 53 (see below).
Is there another way to list only the observations used for the regression?
Any comments are highly appreciated.
Regards
Jessica
