Challenges of sampling and how phylogenetic comparative methods help: with a case study of the Pama-Nyungan laminal contrast
Abstract Phylogenetic comparative methods are new in our field and are shrouded, for most linguists, in at least a little mystery. Yet the path that led to their discovery in comparative biology is so similar to the methodological history of balanced sampling, that it is only an accident of history that they were not discovered by a linguistic typologist. Here we clarify the essential logic behind phylogenetic comparative methods and their fundamental relatedness to a deep intellectual tradition focussed on sampling. Then we introduce concepts, methods and tools which will enable typologists to use these methods in everyday typological research. The key commonality of phylogenetic comparative methods and balanced sampling is that they attempt to deal with statistical non-independence due to genealogy. Whereas sampling can never achieve independence and requires most comparative data to be discarded, phylogenetic comparative methods achieve independence while retaining and using all comparative data. We discuss the essential notions of phylogenetic signal; uncertainty about trees; typological averages and proportions that are sensitive to genealogy; comparison across language families; and the effects of areality. Extensive supplementary materials illustrate computational tools for practical analysis and we illustrate the methods discussed with a typological case study of the laminal contrast in Pama-Nyungan.
期刊介绍:
Linguistic Typology provides a forum for all work of relevance to the study of language typology and cross-linguistic variation. It welcomes work taking a typological perspective on all domains of the structure of spoken and signed languages, including historical change, language processing, and sociolinguistics. Diverse descriptive and theoretical frameworks are welcomed so long as they have a clear bearing on the study of cross-linguistic variation. We welcome cross-disciplinary approaches to the study of linguistic diversity, as well as work dealing with just one or a few languages, as long as it is typologically informed and typologically and theoretically relevant, and contains new empirical evidence.
