Two phylogenetic comparative methods, independent contrasts and generalized least squares models, can be used to determine the statistical relationship between two or more traits. We show that the two approaches are functionally identical and that either can be used to make statistical inferences about values at internal nodes of a phylogenetic tree (hypothetical ancestors), to estimate relationships between characters, and to predict values for unmeasured species. Regression equations derived… Expand
A METHOD FOR ASSESSING PHYLOGENETIC LEAST SQUARES MODELS FOR SHAPE AND OTHER HIGH‐DIMENSIONAL MULTIVARIATE DATA
  • D. Adams
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 2014
TLDR
The new procedure provides a useful means of assessing trait covariation across a set of taxa related by a phylogeny, enabling macroevolutionary biologists to test hypotheses of adaptation, and phenotypic change in high‐dimensional datasets. Expand
A Bayesian extension of phylogenetic generalized least squares: Incorporating uncertainty in the comparative study of trait relationships and evolutionary rates
TLDR
This paper shows how Bayesian statistics facilitates this task while relaxing the homogeneous rate assumption of the well‐known phylogenetic generalized least squares (PGLS) framework, and shows its usefulness by exploring the coevolution of ankle posture and forefoot proportions in Carnivora.

Why the phylogenetic regression appears robust to tree misspecification.
  • E. Stone
  • Mathematics, Medicine
  • Systematic biology
  • 2011
TLDR
This manuscript aims to elucidate how tree misspecification is propagated through a comparative analysis with a focus on the phylogenetic regression under a Brownian motion model of evolution and considers the effect of local phylogenetic perturbations on the regression fit. Expand
TESTING FOR PHYLOGENETIC SIGNAL IN COMPARATIVE DATA: BEHAVIORAL TRAITS ARE MORE LABILE
TLDR
Analysis of variance of log K for all 121 traits indicated that behavioral traits exhibit lower signal than body size, morphological, life-history, or physiological traits, and this work presents new methods for continuous-valued characters that can be implemented with either phylogenetically independent contrasts or generalized least-squares models.

Ancestral State Estimation with Phylogenetic Ridge Regression
TLDR
The RRphylo-noder implementation is particularly appropriate to study phenotypic evolution in the presence of complex phenotypes generated by different processes acting in different parts the tree, and when suitable information about fossil phenotypes is at hand. Expand
Statistical approaches to the problem of phylogenetically correlated data
TLDR
The principles of regression modeling used in this chapter are designed to minimize the problem with interspecific (multi-species) data, where techniques based on the phylogenetic comparative method are used to improve the reliability of inferences with regression. Expand
TESTING FOR PHYLOGENETIC SIGNAL IN COMPARATIVE DATA: BEHAVIORAL TRAITS ARE MORE LABILE
Abstract The primary rationale for the use of phylogenetically based statistical methods is that phylogenetic signal, the tendency for related species to resemble each other, is ubiquitous. WhetherExpand
Multivariate Phylogenetic Comparative Methods: Evaluations, Comparisons, and Recommendations
TLDR
It is concluded that methods summarizing information across trait dimensions, as well as pairwise composite likelihood methods should be avoided, whereas algebraic generalizations of the phylogenetic comparative toolkit provide a useful means of assessing macroevolutionary patterns in multivariate data.

Testing species’ deviation from allometric predictions using the phylogenetic regression
  • J. Smaers, F. Rohlf
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 2016
TLDR
This work simplifies previous computational descriptions of PGLS standard errors in a manner that can be easily generalized toward more complex general linear models and focuses on the implementation of phylogenetic analysis of covariance, which provides a direct test for the equality of intercepts and slopes.

Phylogenetic signal and linear regression on species data
Summary 1. A common procedure in the regression analysis of interspecies data is to first test the independent and dependent variables X and Y for phylogenetic signal, and then use the presence ofExpand

An Introduction to Phylogenetically Based Statistical Methods, with a New Method for Confidence Intervals on Ancestral Values
TLDR
Three phylogenetically based statistical methods are presented, including phylogenetically independent contrasts, Monte Carlo computer simulations to obtain null distributions of test statistics, and phylogenetic autocorrelation, which allow traditional topics in comparative and ecological physiology to be addressed with greater rigor.

The phylogenetic regression.
  • A. Grafen
  • Mathematics, Medicine
  • Philosophical transactions of the Royal Society of London. Series B, Biological sciences
  • 1989
TLDR
One conclusion is that the dates of splits between taxa, even supplemented by rates of neutral gene evolution, do not provide the ‘ true ’ covariance structure, and a pragmatic approach is adopted. Expand
Seeking the evolutionary regression coefficient: an analysis of what comparative methods measure.
  • M. Pagel
  • Biology, Medicine
  • Journal of theoretical biology
  • 1993
TLDR
Comparative statistical techniques are able to recover the historical trends of evolution, that is, the ways in which evolution has proceeded along the branches of the phylogenetic tree, from analysis of the variation among the contemporary species of a phylogeny. Expand
Phylogenies and the Comparative Method
TLDR
A method of correcting for the phylogeny has been proposed, which specifies a set of contrasts among species, contrasts that are statistically independent and can be used in regression or correlation studies. Expand
Procedures for the Analysis of Comparative Data Using Phylogenetically Independent Contrasts
TLDR
Any (continuous) trait that is inherited from ancestors is appropriate for analysis, regardless of the mechanism of inheritance (e.g., genetic or cultural), according to Felsenstein's method. Expand
PHYLOGENIES, SPATIAL AUTOREGRESSION, AND THE COMPARATIVE METHOD: A COMPUTER SIMULATION TEST
  • E. Martins
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1996
TLDR
Brownian motion computer simulation was used to test the statistical properties of a spatial autoregressive method in estimating evolutionary correlations between two traits using interspecific comparative data, showing how diagnostic techniques can be useful in detecting and avoiding such situations, but that such techniques should not be used as definitive evidence that phylogenetic correlation is not present in a set of comparative data.

Truth or Consequences: Effects of Phylogenetic Accuracy on Two Comparative Methods
TLDR
Simulations show independent contrasts to be valid when branch lengths are known, whether or not the topology is known fully, and how the two approaches stand up to incompletely resolved trees and incorrect branch length information—common situations for comparative biologists. Expand

A generalized linear model (GLM) is presented for the analysis of comparative data, which can be used to address questions regarding the relationship between traits or between traits and environments, the rate of phenotypic evolution, the degree of phylogenetic effect, and the ancestral state of a character.
