Analysis focused on estimating a well-known model, the gamma-generalized queuing model (gamma-GQM).
But other researchers say the excess could be an artifact of the way Abazajian and Kaplinghat model the gamma-ray flux, or it could originate from more-mundane sources.
The small magnitude of increase is probably why Bayes factors did not support either the partitioned model or the gamma model, both of which allowed for rate variation.
We ran RAxML with the VT substitution model and the gamma model for rate heterogeneity, parameters which are most suitable for our alignment according to ProtTest (Darriba et al. 2011).
Even though I was surrounded by far pricier models, the Gamma didn't feel out of place.
In other studies, which compare log and Cox proportional hazard models, the Gamma regression model was introduced as the reasonable model across all of the simulation processes [13].
Rate heterogeneity among sites was modelled using the gamma model.
The OLS model and the Gamma with square-root link model had the second best RMSEs, with both estimates and BCIs very close in value.
The general time reversible model of nucleotide substitution was used, with among-site rate variation modeled by a gamma distribution and a proportion of invariable sites (GTR + Γ + I model), with the gamma distribution approximated by 4 equiprobable discrete categories.
