Interpretation of the results of common principal components analyses.

Evolution; international journal of organic evolution - 1 Mar 2002

Houle David, Mezey Jason, Galpern Paul

Abstract excerpt

Common principal components (CPC) analysis is a new tool for the comparison of phenotypic and genetic variance-covariance matrices. CPC was developed as a method of data summarization, but frequently biologists would like to use the method to detect analogous patterns of trait correlation in multiple populations or species. To investigate the properties of CPC, we simulated data that reflect a set of causal...
