Well, either way, it is probably problematic, given the warning
message about the 8 observations being completely determined. You
might drop those cases and see what happens.
I am astonished that Stata has given the F-statistic instead of the
chi-squared one in the second model fitted. This seems to have
occurred just because I deleted the last six variables of the first
model. Having asked two Stata experts, who told me that they had
never seen anything like this, I am hoping that someone on statalist
will be able to clarify the situation for me. Many thanks in advance.
If you want a second opinion, you could try downloading and running
-oglm-. oglm isn't as good about giving you these kinds of warning
messages (I need to work on that!) Whether it would give you an F or
chi-square stat with the 2nd model, I don't know.
