Re: st: repeated time unbalanced panel data

Thanks for the great help.
Your assumptions about the data are correct.

This worked perfectly:
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

The programming below worked great and got me the output that I needed.

I transformed my repeated time unbalanced panel data for in time series: for 
different years, the same individual.

I would really happy with your help on this.
Thank you very much.
