Dear statalist,
I would like to do something that is pretty straight forward, but I do not
have the stata skills to do this and would appreciate some help.
I have an unbalanced panel data set (almost 101.000 observations) which is
too large to work with. The dataset looks like:
Id year y(dependent variable) x1 x2 x3 (many many
covariats)
1 2000
1 2001
1 2002
2 2003
2 2004
3 1998
3 1999
3 2000
3 2001
3 2002
3 2003
3 2004
3 2005
The dataset is already xtset with identifier (ID) and time (year). Because
the original dataset is too large I would like to take a random subsample
(containing of ca. 1000 observation) out of the original dataset. I have
already tried to follow the advices from the FAQ "How can I take random
samples from an existing dataset?", but it does not work for me.
Does somebody could help me to solve this problem?
Best regards
Frauke
