The multispecies coalescent model describes the generation of gene trees from a rooted metric species tree and thus provides a framework for the inference of species trees from sampled gene trees. We prove that the STAR method of Liu et al. (2009) and generalizations of it, are statistically consistent methods of topological species tree inference under this model. We discuss the impact of gene tree sampling schemes for species tree inference using generalized STAR methods and reinterpret the original STAR as a consensus method based on clades.
多物种合并模型描述了从有根度量物种树生成基因树的过程，从而为从采样基因树推断物种树提供了一个框架。我们证明了Liu等人（2009年）的STAR方法及其推广方法，在该模型下是拓扑物种树推断的统计一致方法。我们讨论了使用广义STAR方法进行物种树推断时基因树采样方案的影响，并将原始的STAR重新解释为基于分支的共识方法。
