Table 3:

The demographic parameters of orangutan history with migration for structure (1, 1) (ORAN-STRUCT-MIG model) inferred with different engines in GADMA2. Ground truth includes the simulated parameter values that were obtained from the original study by Locke et al. [30]. Momi2 engine was excluded as it does not support continuous migrations. Log-likelihood values are not comparable between different engines
