# COMPARATIVE METHODS FOR THE ANALYSIS OF CONTINUOUS VARIABLES: GEOMETRIC INTERPRETATIONS

Abstract This study is concerned with statistical methods used for the analysis of comparative data (in which observations are not expected to be independent because they are sampled across phylogenetically related species). The phylogenetically independent contrasts (PIC), phylogenetic generalized least‐squares (PGLS), and phylogenetic autocorrelation (PA) methods are compared. Although the independent contrasts are not orthogonal, they are independent if the data conform to the Brownian… Expand

Analysis of comparative data using generalized estimating equations.

- Medicine, Mathematics
- Journal of theoretical biology
- 2002

A new method is introduced, based on the use of generalized estimating equations (GEE), for the analysis of comparative data, to incorporate a correlation matrix that specifies the dependence among observations in the phylogenetic tree of the studied species. Expand

A METHOD FOR ASSESSING PHYLOGENETIC LEAST SQUARES MODELS FOR SHAPE AND OTHER HIGH‐DIMENSIONAL MULTIVARIATE DATA

- Biology, Medicine

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

DETECTING CORRELATION BETWEEN CHARACTERS IN A COMPARATIVE ANALYSIS WITH UNCERTAIN PHYLOGENY

- Biology, Medicine
- Evolution; international journal of organic evolution
- 2003

A method for performing comparative analyses that is based on an extension of Felsenstein's independent contrasts method, which handles uncertainty in the phylogeny, branch lengths, and other parameters by averaging over all possible trees, weighting each by the probability that the tree is correct.

Comparative Methods as a Statistical Fix: The Dangers of Ignoring an Evolutionary Model

- Mathematics, Medicine
- The American Naturalist
- 2011

Simulations are used to compare two commonly used comparative methods with and without evolutionary basis, respectively: generalized least squares (GLS) and phylogenetic eigenvector regression (PVR), and it is found that GLS methods are more efficient at estimating model parameters and produce lower variance in parameter estimates.

A comparison of metrics for estimating phylogenetic signal under alternative evolutionary models

- Biology, Medicine
- Genetics and molecular biology
- 2012

It is shown that statistical approaches provide valid results and may be still particularly useful when detailed phylogenies are unavailable or when trait variation among species is difficult to describe by more standard Brownian or O-U evolutionary models. Expand

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 of… Expand

Multivariate Phylogenetic Comparative Methods: Evaluations, Comparisons, and Recommendations

- Biology, Medicine
- Systematic biology
- 2018

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.

Phylogenetic logistic regression for binary dependent variables.

- Biology, Medicine
- Systematic biology
- 2010

Analysis of statistical methods for phylogenetic logistic regression in which the dependent variable is binary (0 or 1) and values are nonindependent among species, with phylogenetically related species tending to have the same value of the dependent variables shows that, as with the case for continuous-valued dependent variables, this method should be used when there is the possibility of phylogenetic correlations among species.

PHYLOGENETIC META-ANALYSIS

- Biology, Medicine
- Evolution; international journal of organic evolution
- 2008

A model for phylogenetic meta-analysis is derived, so that data across studies may be summarized with evolutionary history explicitly incorporated and a general statistical template for meta-analytic techniques that can account for attributes that generate nonindependence among studies are provided.

ADAPTIVE CONSTRAINTS AND THE PHYLOGENETIC COMPARATIVE METHOD: A COMPUTER SIMULATION TEST

- Biology
- 2002

It was found that correlations estimated without taking phylogeny into account were often quite poor and never substantially better than those produced by the other tested methods, while Felsenstein's independent contrasts (FIC) method gave the best performance in many cases, even when weak constraints had been acting throughout phenotypic evolution.

PHYLOGENIES, SPATIAL AUTOREGRESSION, AND THE COMPARATIVE METHOD: A COMPUTER SIMULATION TEST

- Biology, Medicine
- Evolution; international journal of organic evolution
- 1996

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.

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

Passengerines exhibit a lower rate of evolution in both body mass and mass‐corrected BMR; passerines also have significantly smaller body masses than their sister clade, which may justify separate, clade‐specific allometric equations for prediction of avian basal metabolic rates. Expand
