Since count models consist in probabilities, they are easily interpretable as sets of likelihoods, in the same way the other types of discrete models are.
Unfortunately, only a small set of likelihood functions can easily be used without resorting to multi-hypothesis filtering methods.
The complete set of Likelihood Ratio Test (LRT) statistics and selective pressure heterogeneity results are provided in Additional files 2 and 3.
The first set of likelihood models that we used, site-specific [ 44], assume variations in the selective pressure across sites but no variations among individual genes.
In the case of a missing parent, or parents, the test conditions on the sufficient statistic for the genotype distribution in each family; where a parent genotype is expressed as a set of likelihoods conditioned upon known offspring genotype(s).
The sets of site likelihoods were then compared by the KH, weighted KH (WKH), SH and SH (WSH) test in Consel 0.1j [ 34].
As shown in the scheme of Figure 3, there is a set of two likelihood calculators for each parallel channel, one of them to calculate the model based log-likelihood for the AE label (E), provided by the AED system, and the other to calculate it for speech.
They revised the set of maximum likelihood estimation procedures proposed by Andreou [8] to estimate the warp factors for each speaker.
In a nutshell, the 95%% level set of the likelihood function is not elliptical, because it is clipped by the edges of Ω. Therefore c must be adjusted to correct for 'level error', which is where the actual coverage is not equal to the nominal coverage.
These were used as input in PhyML [39] to reconstruct a set of maximum likelihood trees by estimating and implementing the GTR + I + G nucleotide substitution model.
