Taxon Sampling and Reverse Successive Weighting

Perfect 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 ...

Successive Sampling and Software Reliability

Two-Phase Sampling and Weighting

Non-response or other missingness may be occurred in various forms. In this paper, we consider unit non-response, and hence make attempts for adjustments by appropriate weighting. Our special exercise is concerned a two-phase sampling case so that, first, a large sample survey has been conducted with a rather general questionnaire. In the end of this face-to-face contact the interviewer has ask...

Increased taxon sampling greatly reduces phylogenetic error.

Several authors have argued recently that extensive taxon sampling has a positive and important effect on the accuracy of phylogenetic estimates. However, other authors have argued that there is little benefit of extensive taxon sampling, and so phylogenetic problems can or should be reduced to a few exemplar taxa as a means of reducing the computational complexity of the phylogenetic analysis....

Inference in Successive Sampling Discovery

A variety of practical problems of nite population inference can be addressed in the framework of successive sampling discovery models { population units are assumed drawn from a superpopulation distribution and then successively sampled according to a speciied`size-biased' selection mechanism. Formal statistical analysis of discovery data under such models is technically challenging, as exempl...
