1. statistical resampling procedures, have been employed with parsimony analysis.
2. Parsimony analysis often returns a number of equally most-parsimonious trees ( MPTs ).
3. For example, in maximum parsimony analysis, there may be many trees with the same parsimony score.
4. It also enables parsimony analysis of contaminated traditions of transmission that would be impossible to evaluate manually in a reasonable period of time.
5. Secondary homology is implied by parsimony analysis, where a character that only occurs once on a tree is taken to be homologous.
6. It's difficult to find parsimony analysis in a sentence. 用parsimony analysis造句挺難的
7. Even if multiple MPTs are returned, parsimony analysis still basically produces a point-estimate, lacking confidence intervals of any sort.
8. By contrast, the combined parsimony analysis and the ML analyses of 28S alone place " Polypodium " within the hydrozoan clade Leptothecata.
9. They later assigned the Antillean monkeys to the tribe Xenotrichini  the Callicebini with extensive anatomical comparisons and by extending their parsimony analysis using PAUP *.

14. ME is closely akin to parsimony, and under certain conditions, ME analysis of distances based on a discrete character dataset will favor the same tree as conventional parsimony analysis of the same data.
15. Finding the optimal least-squares tree with any correction factor is NP-complete, so heuristic search methods like those used in maximum-parsimony analysis are applied to the search through tree space.
16. The bootstrap, resampling with replacement ( sample x items randomly out of a sample of size x, but items can be picked multiple times ), is only used on characters, because adding duplicate taxa does not change the result of a parsimony analysis.
