This means that I observe some contracts with a duration of ten years, but I do not observe a contract signed in the same year with a duration of 3 years (that is, it was binding for only 3 years). OLS estimates are therefore biased, and MLE is needed.

To every ω-consistent recursive class κ of formulae there correspond
recursive class signs r, such that neither v Gen r nor Neg(v Gen r)
belongs to Flg(κ) (where v is the free variable of r).
