The natural complexity of ecological communities regularly lures ecologists to collect elaborate data sets in which confounding factors are often present. Although multiple regression is commonly used in such cases to test the individual effects of many explanatory variables on a continuous response, the inherent collinearity (multicollinearity) of confounded explanatory variables encumbers analyses and threatens their statistical and inferential interpretation. Using numerical simulations, I…

Multicollinearity in spatial genetics: separating the wheat from the chaff using commonality analyses

This review illustrates how commonality analysis (CA), a detailed variance‐partitioning procedure that was recently introduced in the field of ecology, can be used to deal with nonindependence among spatial predictors and strongly urges spatial geneticists to systematically investigate commonalities when performing direct gradient analyses.

Confronting collinearity: comparing methods for disentangling the effects of habitat loss and fragmentation

Estimating the relative importance of habitat loss and fragmentation is necessary to estimate the potential benefits of specific management actions and to ensure that limited conservation resources

Collinearity in ecological niche modeling: Confusions and challenges

It is concluded that Maxent is robust to predictor collinearity in model training, the strategy of excluding highly correlated variables has little impact because Maxent accounts for redundant variables, and coll inearity shift and environmental novelty can negatively affect Maxent model transferability.

Using information theory as a substitute for stepwise regression in ecology and behavior

This work examines three shortcomings of stepwise regression, subjective critical values, model uncertainty, and parameter estimation bias, and argues that, in certain circumstances, the IT approach may be sensitive to these issues as well.

Plotting partial correlation and regression in ecological studies

Abstract. Multiple regression, the General linear model (GLM) and the Generalized linear model (GLZ) are widely used in ecology. The widespread use of graphs that include fitted regression lines to

Coefficient shifts in geographical ecology: an empirical evaluation of spatial and non-spatial regression

A major focus of geographical ecology and macroecology is to understand the causes of spatially structured ecological patterns. However, achieving this understanding can be complicated when using

Habitat is known to influence community structure yet, because these effects are complex, elucidating these relationships has proven difficult. Multiple aspects of vegetation architecture or plant

Collinearity: a review of methods to deal with it and a simulation study evaluating their performance

It was found that methods specifically designed for collinearity, such as latent variable methods and tree based models, did not outperform the traditional GLM and threshold-based pre-selection and the value of GLM in combination with penalised methods and thresholds when omitted variables are considered in the final interpretation.

Red herrings revisited: spatial autocorrelation and parameter estimation in geographical ecology

There have been numerous claims in the ecological literature that spatial autocorrelation in the residuals of ordinary least squares (OLS) regression models results in shifts in the partial

Overlapping landscapes: A persistent, but misdirected concern when collecting and analyzing ecological data

A primary focus of wildlife ecology is studying how the arrangement, quality, and distribution of habitat influence wildlife populations at multiple spatial scales. A practical limitation of

The Use of Regression for Detecting Competition with Multicollinear Data

It is proposed that apparent competition (Holt 1977) and the failure of regression techniques to detect competition when it is known to exist experimentally may be due to the omission or lack of measurement of critical elements of the community matrix.

REGRESSION ANALYSIS OF NATURAL SELECTION: STATISTICAL INFERENCE AND BIOLOGICAL INTERPRETATION

While fitness regression permits direct assessment of selection in a form suitable for predicting selection response, it is suggested that the aim of inferring causal relationships about the effects of phenotypic characters on fitness is greatly facilitated by manipulative experiments.

Review of published ecological studies using path analysis suggests that path analysis is often misused and collinearity is a moderate to severe problem in a majority of the analyses, suggesting that path coefficients may often mislead ecologists about the relative importance of ecological processes.
