Maximum likelihood analyses attempt to infer the evolutionary tree that has the highest probability of observing the data.
These problems may have been due to the way the method was implemented in Stata, where attempts to find a maximum likelihood estimate failed to converge.
We attempted to use Firth's penalised maximum likelihood estimation to address this situation of too few events (deaths) relative to the number of independent variables.
Similar to [47], we then use the maximum likelihood estimation to make a decision on the state of the previously attempted packets.
In their first paper, Ferguson et al. [4] used maximum likelihood methods to fit to the observed incidence time series, but did not attempt to fit to the spatio-temporal pattern of spread.
Despite some attempts to overcome the effects of LBA through the use of a maximum likelihood (ML) approach [ 21- 23] and pruning long branches [ 5, 22], these results have been largely silent on the placement of Polypodium.
CAFE[ 33] was used to attempt to model the birth and death processes in primates with a maximum likelihood value of λ, probability of gene birth or death per million years, calculated as 0.0141.
We aligned the C-terminus of all TFTRs in M. tuberculosis and attempted to establish phylogenetic groupings using widely-employed methodologies such as parsimony, maximum likelihood and neighbour joining.
An attempt in this direction is made in the form of application of existing maximum likelihood linear regression (MLLR) adaptation which has been primarily used to model the differences due to changes in environment or non nativeness of speakers.
