基于偏似然张量的系统进化估计
Phylogenetic estimation with partial likelihood tensors
摘要：
我们提出了一种计算分子遗传学中的似然性的替代方法。我们的方法是基于偏似然张量，这是广义的偏似然向量，在Felsenstein的方法中使用。利用字典排序和偏似然张量，可以获得显着的计算节省。我们通过列举我们的方法和标准方法所需的所有数值计算，在一系列模拟数据上显示了这一点。
英文摘要：
We present an alternative method for calculating likelihoods in molecular phylogenetics. Our method is based on partial likelihood tensors, which are generalizations of partial likelihood vectors, as used in Felsenstein's approach. Exploiting a lexicographic sorting and partial likelihood tensors, it is possible to obtain significant computational savings. We show this on a range of simulated data by enumerating all numerical calculations that are required by our method and the standard approach.
