For panel data models for binary choice we're advised not to try and
manage missing data. I'd always taken that to mean, not to turn SKIP
on. But there's a problem: at least for the rpm models, you don't get
the banner announcing how many observations have been skipped, and
the "Number of Observations" line in the results is wrong (it reports
the current sample size). Turning Skip on seems to solve the problem,
but given the advice, I think it would be nice to be reassured.
So, question: assuming that -999 indicates missing data, are there
any circumstances in which turning SKIP on will lead to incorrect results?
