Figure 2. Relative support for the three models. Cartesian coordinates are a function of log likelihood scores relative to a saturated model (see text). Points near a corner are much better supported by the noted distribution; points at a centre are equally well-described by all three distributions. (A) Performance as a function of sampling intensity and species richness. Redder and larger points include more non-singleton species, characteristic of large sample sizes. (B) Tree inventories. (C) Mammal inventories (gold) and bird inventories (turquoise). (D) Frog and lizard samples (green) and insect inventories (violet).
