st: Re: About Stata
Presumably you have some indicator in the data set that points to the
year of the obserrvation. Just make sure that this variable increases
by one per year, and you can use it for tsset. That is, it could be
1,1,2,3,4 or it could be 1997,1998,1999,2000,2001.
You cannot estimate a VAR without a number of time series
observations. A VAR involves lags. 1998 is not the lag of 2000. If
the consecutive obs. in your sample are 1998 and 2000, define a new
time variable that counts by integers for those years, e.g. 1998=-3,
2000=4 (4th period when you observe the HH). But VAR techniques with
a total of 5 time series obs. are not really workable.
It is more efficient for you to direct such questions to Statalist.
When I am on holiday I will not be reading Statalist, but someone who
can help you will a.s. be available.

Plese, allow me two consultations about Stata.
1. I have balance panel, moreless of 800 observations (households)
years. How I must generate time variable, before tsset?
2. It is possible to use vargranger only with two elapsed years (for
example, 1998 and 2000)?
Thanks in advance
