This is equivalent to modelling of rates.
As a footnote, while high-yield bond rates have been plummeting, preferred yields have been a model of rate stability.
The matrix was partitioned (i.e., ITS vs. rpL16 intron) with a gamma model of rate heterogeneity and proportion of invariable sites estimated by the program.
The formulation of RCM is carried out, considering the design challenges and the execution model of rate controlling factor in future Internet architecture.
Therefore, we also studied mutational saturation under a model of rate variation between synonymous sites.
The model of rate heterogeneity was set to gamma distributed rates with eight gamma rate categories and the alpha parameter estimated from the data set.
All free model parameters were estimated by RA×ML using the GAMMA+P-Invar model of rate heterogeneity with an ML estimate of the alpha-parameter.
The uncorrelated Bayesian model of rate change implemented in BEAST ver. 1.4.4 [13] was used to estimate divergence times and to determine rates.
Here I used the Bayesian approach detailed below to determine these rates under an uncorrelated lognormal model of rate change [13].
I assumed the uncorrelated lognormal (UCLN) prior model of rate change, and a Yule or "pure-birth" prior process to model speciation.
All phylogenetic analyses were computed assuming a gamma model of rate heterogeneity [67] with four classes of variable sites and one class of invariable site (4Γ+I).
