Confidence Limits on Phylogenies: an Approach Using the Bootstrap.
The recently-developed statistical method known as the "bootstrap" can be used to place confidence intervals on phylogenies. It involves resampling points from one's own data, with replacement, to create a series of bootstrap samples of the same size as the original data. Each of these is analyzed, and the variation among the resulting estimates taken to indicate the size of the error involved ...
متن کاملImproved bootstrap confidence limits in large-scale phylogenies, with an example from Neo-Astragalus (Leguminosae).
Phylogenetic analyses of large data sets pose special challenges, including the apparent tendency for the bootstrap support for a clade to decline with increased taxon sampling of that clade. We document this decline in data sets with increasing numbers of taxa in Astragalus, the most species-rich angiosperm genus. Support for one subclade, Neo-Astragalus, declined monotonically with increased ...
متن کاملCombinability of phylogenies and bootstrap confidence envelopes.
Recently, Lutzoni (1997) used a test described by Rodrigo et al. (1993; hereinafter referred to as the RKB3 test) to compare phylogenies constructed by using ribosomal RNA gene sequences (rDNA) and intergenic transcribed spacer sequences (ITS) from a group of related basidiomycete species. Lut-zoni discussed the relationships amongst the species, but he also commented extensively on the RKB3 te...
متن کاملSimultaneous confidence intervals based on the percentile bootstrap approach
This note concerns the construction of bootstrap simultaneous confidence intervals (SCI) for m parameters. Given B bootstrap samples, we suggest an algorithm with complexity of O(mB log(B)). We apply our algorithm to construct a confidence region for time dependent probabilities of progression in multiple sclerosis and for coefficients in a logistic regression analysis. Alternative normal based...
متن کاملBOOTSTRAP CONFIDENCE INTERVALS 1 BootES : An R Package for Bootstrap Confidence Intervals on Effect Sizes
Bootstrap Effect Sizes (bootES; Gerlanc & Kirby, 2012) is a free, open source software package for R (R Development Core Team, 2012), which is a language and environment for statistical computing. BootES computes both unstandardized and standardized effect sizes (such as Cohen’s d, Hedges’s g, and Pearson’s r), and makes easily available for the first time the computation of their bootstrap CIs...
