st: cross-sectional time series data
I would like to get suggestions concerning cross-sectional time series data.
My estimation model consists of 10 individual units, each sharing the same
variables and for the same 19-year time period. Where I am confused is whether
to consider this as Panel data or cross-sectional time series data. Certain
literature treats Panel and cross-sectional time series as one in the same,
while others indicate that they are not.
Further complication is knowing which Stata commands to use.
Initially I ran this command
. xtreg y x1 x2 x3 x4 x5 x6 x7, re
to test to see whether GLS is necessary or simple OLS will do for the
Secondly I ran
to discriminate against eitehr the Pool Model and the Random Effects Model and
the results indicated pooled model was not appropriate.
I then ran the Hausman test in order to determine betweem the Random Effect
Model or Fixed effects model:
The results indicated that the Fixed effects is appropriate.
Are these the right steps and commands to apply to cross-sectional time series
data? Or should I use the xtgls or the xtgee commands?
I would greatly appreciate your suggestions in clarifying this confusion.
