-suest- is a very general program, so it needs to use very
general rules to detect violations: one of these is apparantly
that the number of equations needs to be equal in both models,
which makes sense to me. In the example you gave the first
model had 5 equations and the second model had 4, i.e. you
lost private as an outcome.
Hope this helps,
Maarten
