I have an unbalanced panel and would like to test unit root. I found
xtfisher and would like to know more about this command. Could someone
recommend a good article/paper that discusses its econometrics and
possibly compares its results with ipshin and similar panel unit root
tests?
Also, I am hesitant about using impute to fill in missing values due to
the increased measurement error, but many studies do use techniques
to fill in missing data. I would appreciate if someone shares his/her
views/thoughts on filling in missing data using impute and ipolate.
Thank you in advance
Zamira
