I am doing a panel study on determinants of fdi of top 10 countries that receive the maximum fdi inflows over the time period 1990-2019. N = 10 and T = 30. I did a panel unit root test and variables turned out to be stationary. There was cointergration among variables. I initially used xtreg command in stata to get results. But now I am confused as to is this correct or not. Any help will be highly appreciated.
