  1. Likelihood-ratio test between pairs of models. Null model is d0 step model (where d0 equals 1, 2, or 3) while the alternative model is a d1 step model (where d1 = d0+1), in the regimes of weak and medium induction. For p-values 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.
