The supplemental material of the study you cited only discusses tree-based methods, but perhaps you can further enlighten me if I'm missing something!Glorhttps://www.blogger.com/profile/17707197225963721646noreply@blogger.comtag:blogger.com,1999:blog-1871542942842750523.post-40553350416568119902009-11-23T10:52:43.622-05:002009-11-23T10:52:43.622-05:00Be sure to look at the supplemental material from ...Be sure to look at the supplemental material from Gray et al. for the description of their (non-tree-free) construction methods.<br /><br />DOI: 10.1126/science.1166858Unknownhttps://www.blogger.com/profile/11909162561178775930noreply@blogger.comtag:blogger.com,1999:blog-1871542942842750523.post-21715880305395383762009-11-21T17:59:18.022-05:002009-11-21T17:59:18.022-05:00I've been dabbling with applying phylogenetic ...I've been dabbling with applying phylogenetic methods to language evolution problems, and at least half-heartedly following the literature. I'd be very surprised if this isn't the first study to use Structure-like population assignment and admixture analyses.

I was trying to speak specifically of tree-free clustering algorithms implemented in programs like Structure. That said, I wouldn't be surprised if Structure has also been used previously to investigate language evolution, I just couldn't find any such studies in quick Web of Science and Google searches.Glorhttps://www.blogger.com/profile/17707197225963721646noreply@blogger.comtag:blogger.com,1999:blog-1871542942842750523.post-17819557016863787642009-11-21T09:50:00.614-05:002009-11-21T09:50:00.614-05:00Although the use of phylogenetic methods in quanti...<i>Although the use of phylogenetic methods in quantititive comparative linguisitics isn't new, this new study is, to my knowledge, <b>the first</b> to use the Bayesian clustering algorithms</i><br /><br />cough... doi:10.1038/nature02029 ... cough...
