Dear all,

I hope someone could help me with my issue. Although I have gathered all my data to be eligible for panel-data analysis, I have realized that I would need a time series analysis for each country respectively. Is there any command that would either allow me time series regression from panel data or reshape my data such that I would have the Date it is now, but each variable is country-specific, i.e., I could generate a variable chgn2y_1 which is the 2-year change for the country "one"?
