Title: 通过结果的一致性评估系统发育分析的策略

Abstract: I propose an approach to identify, among several strategies of phylogenetic analysis, those producing the most accurate results. This approach is based on the hypothesis that the more a result is reproduced from independent data, the more it reflects the historical signal common to the analysed data. Under this hypothesis, the capacity of an analytical strategy to extract historical signal should correlate positively with the coherence of the obtained results. I apply this approach to a series of analyses on empirical data, basing the coherence measure on the Robinson-Foulds distances between the obtained trees. At first approximation, the analytical strategies most suitable for the data produce the most coherent results. However, risks of false positives and false negatives are identified, which are difficult to rule out. Show Chinese abstract

Abstract: 我提出一种方法，在多种系统发育分析策略中，识别出产生最准确结果的策略。 该方法基于这样一个假设：一个结果从独立数据中重复的次数越多，它就越能反映分析数据中共有的历史信号。 在这一假设下，分析策略提取历史信号的能力应与获得结果的一致性呈正相关。 我将这种方法应用于对实证数据的一系列分析，将一致性度量基于获得的树之间的Robinson-Foulds距离。 初步来看，最适合数据的分析策略会产生最一致的结果。 然而，发现了假阳性与假阴性的风险，这些风险难以排除。
