Words similar to log-likelihood
Example sentences for: log-likelihood
How can you use “log-likelihood” in a sentence? Here are some example sentences to help you improve your vocabulary:
They computed a test statistic t(A,B,x) for each sequence x as the difference of log-likelihood ratio dissimilarity measures, D ( A , x ) = -2logλ( A , x ), for two data sets, a control set A and an outgroup B , such that t(A,B,x) = D(A,x) - D(B,x) . A negative value for t indicates that the sequence more closely resembles words from A ; conversely, a positive value indicates a likely contaminant related to B . (Dissimilarity is conceptually related to distance.
Statistically, equation (2) is a mixture model in which each component is represented by a genotype within a full-sib family [ 16 17 18 ] . The maximum likelihood estimates for θ = ( μ , σ 2, p ) can be obtained using the EM algorithm [ 19 20 ] . At the t th step of the EM sequence, the expected log-likelihood is proportional to
Wald's statistics and log-likelihood ratios of the models were used to identify variable significance and model fit.
As local maxima can be found by the EM algorithm, it is desirable to run the algorithm multiple times with various starting values and choose the estimate as the one resulting in the largest log-likelihood.
Also, from the log-likelihood values, there is a dramatic change when g is increased from 1 or 2. However, from g = 3 log L increases very slowly.
