Pantelis Z. Hadjipantelis, Nick S. Jones, John Moriarty, David Springate, Christopher G. Knight

摘要:

许多生物学特征的进化兴趣不是标量变量,而是连续函数。在这里,我们使用系统发育高斯过程回归模拟功能值性状的演变。鉴于功能值的数据,只有从一个进化树的提示,并利用独立主成分分析(IPCA)作为一种方法,降维,我们构造分布估计祖先功能值性状,并估计参数描述其进化动力学。

英文摘要:

Many biological characteristics of evolutionary interest are not scalar variables but continuous functions. Here we use phylogenetic Gaussian process regression to model the evolution of simulated function-valued traits. Given function-valued data only from the tips of an evolutionary tree and utilising independent principal component analysis (IPCA) as a method for dimension reduction, we construct distributional estimates of ancestral function-valued traits, and estimate parameters describing their evolutionary dynamics.
