Dear Stata users,
Lets say I have the above data set. I want to create a variable which measures the difference between the gdp in year 1970 and gdp in 1965 for each country. That is if "diff" is the new variable it would be diff = gdp(1970)-gdp (1965) for each country.
I am a new user and already spent hours on this. I would much appreciate your help.
Thanks in advance
