partitioned dataset won't run EGLS
Posted: Wed Oct 30, 2019 11:26 am
Hello. I have a data set that runs EGLS just fine, (280 cross section units and mostly 8 years but unbalanced).
I've eliminated a large number of observations pursuant to a research objective and also removed observations representing only a single year.
Model no longer runs with reduced data and I get this message: "Positive or non-negative argument to function expected in
computation of group weight (variance)."
What might I be missing?
Many thanks, eljayski
