Re: st: repeated time unbalanced panel data

[Daniel Lawson <dlawson1@nd.edu>]

I don't know if I understood the data structure correctly, but if I do, 
this should produce a tsset that you can then use with xtreg or other 
panel data tools.  There's probably a better way to do this than what 
I'm suggesting.

gen individual_ID = 1
replace individual_ID = individual_ID[_n-1] + 1 if (_n>1) & (year[_n] 
== year[_n-1])
quietly sum individual_ID
replace individual_ID=individual_ID + (id - 1)*r(max)
tsset individual_ID year

Peace,
Daniel Lawson
