Dear all,

In some literature reviews, I see that panel FMOLS/DOLS will be employed to estimate cointegration relationship (long-run relationship) between variables (in stata, xtcointreg is used to run these models).

However, with xtpmg, I can also gain the long-run cointegrating relationship between the variables.

I would like to ask whether or not there are difference between 2 approaches to estimate cointegration relationship between variables? If yes, which approach should I use? Because when I try both approaches, I am given very significantly different results
