Taxon: Is It Taxonic? 1 Taxon: Is It Taxonic?
Taxometric method, invented by Paul Meehl (1965) and developed by him and a number of colleagues, is a family of procedure for subjecting parts of a certain class of theories to risky tests. The theories in question postulate the existence of a latent category, the taxon, and its complement class. A taxon is negatively defined as a " non-arbitrary latent category. " It does not appear to be pos...
متن کاملPerfect taxon sampling and phylogenetically decisive taxon coverage
In a recent study, Steel and Sanderson defined and characterized phylogenetically decisive sets of taxon sets. A set is called phylogenetically decisive if regardless of the trees chosen for each of its taxon sets, as long as these trees are compatible with one another, their supertree is always unique. This implies that the sampled taxon sets always lead to a unique supertree, regardless what ...
متن کاملWhat's in a taxon?
Whether taxometrics yields inferential knowledge to something latent is partly but not wholly a semantic question. Although the single variables are manifest indicator scores of individuals, the statistics computed from them via postulates of the formalism are not mere data summaries and will be incorrect or meaningless if the structural conjectures are false. The unidirectional derivability fr...

متن کاملCompetition asymmetry with taxon divergence.
Most organisms experience competition for resources, probably most of the time. As the structure and requirements of closely related species are generally liable to be more similar than in distantly linked species, Darwin suggested that the potential for competition was greater in the former. Since that time, studies have concentrated on interactions of either conspecifics or congeneric species...
