Fisher-type test for unit root

[Souryabrata Mohapatra]

Hi,
I run a panel model using PCSE.
Before that, I want to check for stationarity.
My panel data is unbalanced, for 28 years (2000 observations in total).
Can I use a Fisher-type test for unit root?

Yes, both the Fisher type test and IPS can accommodate unbalanced panel data.
