Bootstrap test of phylogeny
WebMay 1, 2002 · It was applied to maximum-likelihood tree selection for obtaining the confidence set of trees. The AU test is based on the theory of Efron et al. (Proc. Natl. Acad. Sci. USA 93:13429–13434; 1996), but the new method provides higher-order accuracy yet simpler implementation. The AU test, like the Shimodaira–Hasegawa (SH) test, adjusts … WebMay 1, 2013 · Highlights Evaluating the reliability of estimated phylogenetic trees is of key importance. To date, computational restrictions have precluded the use of DBP in phylogenetics. We develop a method called the speedy double bootstrap (sDBP) to address this. sDBP is third-order accurate. Computationally, sDBP is significantly faster …

WebUnlike the bootstrap, the interior-branch test has the same statistical properties irrespective of the number of sequences used when a predetermined tree is considered. Therefore, the interior-branch test appears to be preferable to the bootstrap test as long as unbiased estimators of evolutionary distances are used. WebNov 25, 2002 · These results indicate that bootstrap probabilities are more suitable for assessing the reliability of phylogenetic trees than posterior probabilities and that the mammalian and plant phylogenies may not have been fully resolved. ... the bootstrap test of this null hypothesis is quite complicated (19, 21).
