Hello Statalist scholars,

I have an unbalanced panel data in which I am trying to run the 'xtdpdsys' and 'xtdpd' commands. But it gives me error saying NO OBSERVATIONS. I am not sure where I am going wrong. Currently, I am running an INTERCEPT only model. 

Any thoughts/ ideas is very much appreciated!

Thank you!
