Dear all,
I'd like to run a unit root test for a panel data. The data is unbalanced. The panel variable(id) is 9976(max) and time variable(year) is 9.
I tried to run the ADF test but it is said in red "sample may not include multiple panels". Also, LLC is said not suitable for unbalanced data.
What I'm trying to do now is: use "gen t=_n" command to treat the dataset as a time series and then use ADF to test the unit root. Correct me if I'm wrong.
what's more, is it necessary to test the unit root for a panel dataset? Thanks for your time.
