These criteria can offer solid alternative solutions for the model selection problem in scenarios with limited observability andnoisy data.
By 2100, net ecosystem exchange was projected to increase by ca. 28%, indicating an increase in the ecosystem's capacity to accumulate C. Substantial proportions of the variability in all pools and fluxes were explained by mortality assumption and model selection but not by climate change scenario.
The fact of the matter is that organisms existed in the past that contained ancestral copies of these fundamental proteins, and that all known extant life has inherited descendant versions of these proteins from these ancestral organisms (at least that is the scenario that my model selection tests strongly support).
Finally, we tested scenarios in which the statistical model deviated from the true genetic model used for simulation, i.e. when model selection failed to select the right model (Table 2).
To characterize changes in the distribution of clonal susceptibilities in the population, we examined nine models representing three different selection scenarios: null models assuming no change in distribution through time (i.e., no selection; models 1 and 2; Table 1), directional selection (models 3 and 4), and disruptive selection (models 5 9).
The tests performed on decoy sets are representative of a possible clustering scenario in the context of most representative model selection.
Statistical support for putative hybridization scenarios was assessed with the method proposed by Kubatko [ 40], in which statistical model selection techniques (e.g., AIC) are used to compare species trees that may or may not include hybridization scenarios.
In such scenarios there are strong arguments for making use of data-driven model selection methods (ideally in conjunction with subject matter knowledge if there is any).
The results for the 16 scenarios are summarized in the Additional file 1. AIC was used for model selection.
A key to the weights used in each selection scenario for the respective traits is provided; a selection rate of 2% was used in the model.
