Statistical Analysis of Character Based Classification



Anything useful for dino classification in this approach?  Just curious.  (The article is from the science-mailer; editor's choice.)
 
ORGANISMAL BIOLOGY: Statistics and Systematics
---------------------------------------------------------------------------
Andrew M. Sugden

Biologists since Linnaeus have routinely used the species as the
fundamental unit of classification. Despite the many recent advances of
phylogenetic and systematic methodology, the vast majority of species are
delimited on the basis of a very small number of preserved specimens that
may not be representative of the true range of variation. Obtaining the
ideal sample sizes or conducting detailed morphological and molecular
analyses on more than a tiny proportion of the world's species is
impractical by any yardstick. Can statistical methods help?

Wiens and Servedio present a new statistical model that allows systematists
using traditional character-based methods to determine whether they have
sampled enough characters (usually morphological) or individuals to
diagnose species differences with confidence. The model promises hope for
more standardized approaches to traditional taxonomic methods, still used
for the bulk of systematic work. -- AMS
