st: How do I define this data as a panel?
Hello,
My data has the following "shape":
Country Year Company Industry Variables
Country1 2000 CompanyA IndX V1 V2 VN
Country1 2000 CompanyB IndY V1 V2 VN
Country1 2001 CompanyA IndX V1 V2 VN
...
Country1 2006 CompanyD IndZ V1 V2 VN
.
Country2 2000 CompanyB IndY V1 V2 VN
..
Country2 2006 CompanyJ IndX V1 V2 VN
...
CountryN 2006 CompanyN IndN V1 V2 VN
When I try to define it as a panel using country and year as the panel and time variables respectively, I get the error message " repeated time values in sample". Obviously the combination of country and year is not uniquely defining each observation. What should I do in this case to define this data as a panel in order to utilize the --xt-- family of commands?
Your help and suggestions are appreciated.
Regards
Ali Shahzad
