Polytomies and phylogenetically independent contrasts: examination of the bounded degrees of freedom approach.

Systematic biology - 1 Sept 1999

Garland T, Díaz-Uriarte R

Abstract excerpt

We examined the effect of soft polytomies on the performance (Type I error rate and bias) of Felsenstein's (1985; Am. Nat. 125:1-15) method of phylogenetically independent contrasts for estimating a bivariate correlation. We specifically tested the adequacy of bounding degrees of freedom, as suggested by Purvis and Garland (1993; Syst. Biol. 42:569-575). We simulated bivariate character evolution under Brownian...
