Phylogenetic Analyses of the Evolution of Continuous Characters

9509343加兰这项研究将开发和测试基于遗传学的统计方法，试图解释数据集的独立性，特别是连续变量字符的演变。将强调两种分析方法：遗传学独立的对比，最广泛使用和最好的理解，目前可用的方法，和系统发育随机化，一种新的方法，将开发，并有可能取消一些批评以前在遗传学为基础的统计方法。 将制作基于PC的计算机程序，允许非专业人员进行系统发育比较分析;这些程序也可用于本科或研究生阶段的教学。这些程序和附带的文档免费分发。 ***

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. ***
