Follow-up Comment #4, bug #48040 (project pspp):
[comment #3 comment #3:]
> Sorry to raise this from the dead, but this issue hit me today when looking
at a student's problem and comparing SPSS output to PSPP.
>
> PSPP does not include the intercept for a balanced, but fractional design. I
think that is a bug.
>
> Of a certainty, there is a real intercept (I put it there in the model that
generates the data!) and it is knowable and testable, and not including it in
the model greatly affects the analysis.
