绝对模型拟合检验在基于模型的推断中至关重要,因为结构不良的模型可能导致有偏的参数估计。在贝叶斯推理中,后验预测模拟可以用来测试绝对模型拟合。然而,由于缺乏方便灵活的软件,这种测试在系统发育推断中并不普遍。在这里,我们描述了我们新实施的模型拟合测试,使用后验预测测试,基于数据和基于推理的测试统计,在遗传学软件RevBayes中。这种新的实现方式通过用户友好和灵活的界面提供了大量的模型可供使用。
Abstract Tests of absolute model fit are crucial in model‐based inference because poorly structured models can lead to biased parameter estimates. In Bayesian inference, posterior predictive simulations can be used to test absolute model fit. However, such tests have not been commonly practiced in phylogenetic inference due to a lack of convenient and flexible software. Here, we describe our newly implemented tests of model fit using posterior predictive testing, based on both data‐ and inference‐based test statistics, in the phylogenetics software RevBayes. This new implementation makes a large spectrum of models available for use through a user‐friendly and flexible interface.
