plm issues: error for "within" or "random", but not for "pooling"
Dear all
I am working on unbalanced panel data and I can readily fit a
"pooling" model using plm(), but not a "within" or "random" model.
Reproducing the examples in vignette("plm") and in the AER package I
encountered no such issues.
##unfortunately I cannot disclose the data, and it is too big anyway
