Likelihoodratio test between pairs of models. Null model is d_{0 }step model (where d_{0 }equals 1, 2, or 3) while the alternative model is a d_{1 }step model (where d_{1 }= d_{0}+1), in the regimes of weak and medium induction. For pvalues smaller than 0.01, it is generally accepted that the null model should be rejected in favour of the alternative. The single step model is insufficient in both regimes.
