Panel cointegration test, where N>T

[win]

Hi,

I am trying to conduct panel cointegration test with eviews, but it shows "insufficient number of observations".

My balanced panel has N=7 and T=4. My guess is that the observation for T=4 is insufficient. But if there is no additional information on T, is there any alternative to test for stationarity in the data? Please advise.

Thank you.
