Total Evidence, Average Consensus and Matrix Representation with Parsimony: What a Difference Distances Make
Matrix representation with parsimony (MRP) can be used to combine trees in the supertree or the consensus settings. However, despite its popularity, it is still unclear whether MRP is really a consensus method or whether it behaves more like the total evidence approach. Previous simulations have shown that it approximates total evidence trees, whereas other studies have depicted similarities wi...
متن کاملProperties of matrix representation with parsimony analyses.
Baum (1992) and Ragan (1992b) independently devised a method that uses additive binary coding and parsimony to combine trees derived from di erent data sets, a procedure Ragan termed matrix representation with parsimony analysis (MRP). Because the method utilizes the topology of source trees rather than the orig inal data, (1) trees derived from di erent data types (e.g., molecular sequences,...
متن کاملTaxonomic congruence versus total evidence, and amniote phylogeny inferred from fossils, molecules, and morphology.
Taxonomic congruence and total evidence are competing paradigms in phylogenetic inference. Taxonomic congruence focuses on deriving a consensus from the results obtained from separately analyzed data sets, whereas total evidence uses character congruence in the search for the best-fitting hypothesis for all of the available character evidence. Explicit or implicit use of taxonomic congruence is...
متن کاملAssessment of the accuracy of matrix representation with parsimony analysis supertree construction.
Despite the growing popularity of supertree construction for combining phylogenetic information to produce more inclusive phylogenies, large-scale performance testing of this method has not been done. Through simulation, we tested the accuracy of the most widely used supertree method, matrix representation with parsimony analysis (MRP), with respect to a (maximum parsimony) total evidence solut...
متن کاملCanonical forms for complex matrix congruence and *congruence
Canonical forms for congruence and *congruence of square complex matrices were given by Horn and Sergeichuk in [Linear Algebra Appl. 389 (2004) 347–353], based on Sergeichuk’s paper [Math. USSR, Izvestiya 31 (3) (1988) 481–501], which employed the theory of representations of quivers with involution. We use standard methods of matrix analysis to prove directly that these forms are canonical. Ou...
