Table 3 Total log-likelihood of the target function (Eq. 1) on training datasets

From: Improved mitochondrial amino acid substitution models for metazoan evolutionary studies

  Metazoan Vertebrate Invertebrate
mtZoa (initial model) −1.23427e + 07 −5.50036e + 06 −6.85299e + 06
First iteration −1.21987e + 07 −5.32959e + 06 −6.77590e + 06
Second iteration −1.21987e + 07 −5.32671e + 06 −6.77536e + 06
Third iteration (final model) −1.21987e + 07 −5.32671e + 06 −6.77536e + 06
AIC/site 0.795 1.456 1.232
BIC/site 0.790 1.430 1.220
  1. AIC/site (BIC/site) is the AIC (BIC) improvement per site of the final model in comparison to the initial model mtZoa
  2. There is no likelihood improvement after two iterations
