Analyzing large data sets in reasonable times: solutions for composite optima

Open access
Goloboff, Pablo A.·1999·Cladistics

Abstract

New methods for parsimony analysis of large data sets are presented. The new methods are sectorial searches, tree‐drifting, and tree‐fusing. For Chase et al. 's 500‐taxon data set these methods (on a 266‐MHz Pentium II) find a shortest tree in less than 10 min (i.e., over 15,000 times faster than PAUP and 1000 times faster than PAUP*). Making a complete parsimony analysis requires hitting minimum length several times independently, but not necessarily all “islands” for Chase et al. 's data set, this can be done in 4 to 6 h. The new methods also perform well in other cases analyzed (which range from 170 to 854 taxa).

  • A common problem in palaeontological studies is the extremely large numbers of equally parsimonious trees (due to missing entries), but the consensus stabilization procedure can produce an accurate consensus without finding all equally possible most parsimonious trees.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
