利用不变量构建系统发育树

Using invariants for phylogenetic tree construction

Nicholas Eriksson

摘要:

系统发育不变量是系统发育树上马尔可夫模型的联合概率分布中的某些多项式。这样的多项式在代数统计学领域具有理论意义,它们也具有实际意义--它们可以用来构建系统发育树。本文是对系统发育不变量实际使用中涉及的代数、统计和计算挑战的独立介绍。我们调查了相关文献,并提供了一些部分答案和许多悬而未决的问题。

英文摘要:

Phylogenetic invariants are certain polynomials in the joint probability distribution of a Markov model on a phylogenetic tree. Such polynomials are of theoretical interest in the field of algebraic statistics and they are also of practical interest--they can be used to construct phylogenetic trees. This paper is a self-contained introduction to the algebraic, statistical, and computational challenges involved in the practical use of phylogenetic invariants. We survey the relevant literature and provide some partial answers and many open problems.
