st: xtpcse - "no time periods are common to all panels"
Date

I have panel data for about 120 countries, unbalanced (the number of
years ranges from 3 to 20). I set it up with "xtset panel year." But
when I try to run -xtpcse- I get this error message: "no time periods
are common to all panels, cannot estimate disturbance covariance matrix
using casewise inclusion." But I know that that the panels do include
common years. Most of the panels include the same 15 - 16 years. Does
anyone have experience with this problem?
Thanks,
Wayne
