- Statistical power comparisons among alternative morphometric methodsF J Rohlf

Department of Ecology and Evolution, State University of New York, Stony Brook, NY 11794 5245, USA*Am J Phys Anthropol*111:463-78. 2000..The type I error rate was also often not correct for this method. Results for more than three landmarks are also presented. The implications of the results for practical applications of morphometrics are discussed... - Comparative methods for the analysis of continuous variables: geometric interpretationsF J Rohlf

Department of Ecology and Evolution, State University of New York at Stony Brook, 11794 5245, USA*Evolution*55:2143-60. 2001..Although the PA method is a generalized least-squares procedure, it cannot be made equivalent to the PGLS method using a phylogenetic model... - Use of two-block partial least-squares to study covariation in shapeF J Rohlf

Department of Ecology and Evolution, State University of New York, Stony Brook, New York 11794 5245, USA*Syst Biol*49:740-53. 2000..Examples are given to show its usefulness in comparing two sets of variables--especially when one or both of the sets of variables are shape variables from a geometric morphometric study... - Computing the uniform component of shape variationF James Rohlf

Nat. Acad. Sci. 95, 4121). These results and their implications for the application of different geometric morphometric methods are discussed... - A comment on phylogenetic correctionF James Rohlf

Department of Ecology and Evolution, State University of New York at Stony Brook, Stony Brook, New York 11794 5245, USA*Evolution*60:1509-15. 2006..Estimates of correlations are only slightly biased (and in the opposite direction that many expect)... - Ecological character displacement in Plethodon: biomechanical differences found from a geometric morphometric studyD C Adams
