RE: st: lag vars

[Nick Cox <n.j.cox@durham.ac.uk>]

Not necessarily. 

bysort pid (time) : gen poor0 = poor[1] 

More importantly, there are all sorts of logic tangles opening up here given that -poor0- and -poor- have inbuilt overlap.

I found the solution:
- poverty status in time 0--> by pid: gen poor0 = poor[1] // poverty
status at start

Thanks!
