Phylogenetic Analyses of the Evolution of Continuous Characters

这项研究将开发和测试基于系统发育的统计方法，这些方法试图解释数据集的独立性，特别是连续可变字符的进化。将强调两种分析方法：系统发育独立对比，这是目前可用的方法中最广泛使用和最了解的方法，以及系统发育随机化，这是一种将被开发的新方法，它有可能消除以前针对基于系统发育的统计方法的一些批评。%%%将产生基于个人电脑的程序，允许非专业人员进行系统发育比较分析；这些程序也可以用于本科或研究生水平的教学。这些程序和附带的文档是免费分发的。＊＊＊

9509343 Garland This research will develop and test phylogenetically-based statistical methods which attempt to account for the independence of datasets, especially the evolution of continuously variable characters. Two analytical methods will be emphasized: phylogenetically independent contrasts, the most widely used and best understood of currently available methods, and phylogenetic randomization, a new method that will be developed and which has the potential to nullify a number of criticisms previously leveled at phylogenetically-based statistical approaches. %%% PC-based computer programs that allow non-specialists to perform phylogenetic comparative analyses will be produced; these programs can also be used in teaching at the undergraduate or graduate level. These programs and accompanying documentation are distributed free of charge. ***
