Discriminate Compatibility Measures and the Reduction Routine
Preview not available

Abstract

Discriminate compatibility measures are introduced. The character discriminate compatibility and the average character discriminate compatibility measures are used in weighted parsimony analysis in an iterative procedure, the reduction routine, to build trees. The data set discriminate compatibility measure is used to order and polarize characters. The average data set discriminate compatibility measure is used to measure the fit of different data sets and different user trees. Three inadequacies in the Le Quesne compatibility tests (Le Quesne, 1969, Syst. Zool. 18:201-205; 1979, Syst. Zool. 28:92-94) as applied by Penny and Hendy (1985, Cladistics 1:266-272; 1986, Mol. Biol. Evol. 3:403-417) and Sharkey (1989, Cladistics 5:63-86) are discussed.
