st: lag vars

[Sabrina Carrossa <carrossa@gmail.com>]

Dear all,

I have a three waves panel Db:
2004 (t0)
2005 (t1)
2006 (t2).

I wish to use a probit model (xtprobit) to analyze the TSD of poverty,
and I need to specify some lagged variables such as:
- the lagged poverty status
- the poverty status in time 0
- the current employment status (employed or not)
- the employment status in t2

I know that I can refer to the lagged poverty status by typing:
"l.poor", but what about the other variables?
Should I compute them by gen/egen commands? Is there a more handy and
quick way to obtain them?

Thanks. Any suggestions would be greatly appreciated!!!
