African fossil tali: Further multivariate morphometric studies
American Journal of Physical Anthropology, 1976AbstractAnalysis of measurements from the tali of 21 individual fossil primates from Africa shows that the specimens fall into five clearly defined groups. Accordingly, these specimens have been included as groups along with extant species in a subsequent canonical analysis thus allowing the fossils to play their part in the determination of the ...

Multivariate normality in morphometric analysis
Journal of the International Association for Mathematical Geology, 1971Data on some living (salamanders and grasshoppers) and fossil (Devonian brachiopods) animals are analyzed by means of recently developed methods for the large-scale treatment of multivariate normality. Multivariate nonnormality was found to exist in all situations, even if the univariate deviations in the skewness and kurtosis statistics proved to be ...

Multivariate allometry as a model of morphometric harmony of four skinfolds in the newborn
American Journal of Human Biology, 1992AbstractThe concept of harmony in a set of anthropometric dimensions is identified with the notion of minimum variance associated with a function of several variables in those dimensions. When the chosen function is linear in the natural logarithms of the variables, the resulting model is the well‐known multivariate allometry and the notion of minimum ...

An empirical assessment and illustration of some multivariate morphometric techniques
Journal of the International Association for Mathematical Geology, 1978An artificial data set is used to illustrate the morphologic properties of some common multivariate techniques and consideration of three common situations. The first concerns a sample showing no obvious groupings. In this situation principal components (or coordinates) and factor analyses give a logical ordination of form variation; cluster analysis ...

The main goal of morphometrics is to study how shapes vary and their covariance with other variables. Even though morphometrics can be used to describe the form of any object it is mostly used in biology to describe organisms.

Geometric morphometrics are a class of multivariate methods for measuring and analyzing the shapes of objects. Geometric morphometrics are distinctive in that they use Cartesian coordinates (x, y, z) of landmark points in place of linear measurements as ...

Multivariate Analysis of Covariance in Morphometric Studies of the Reproductive Cycle
Canadian Journal of Fisheries and Aquatic Sciences, 1993A new approach for analysing morphometric data of reproductive cycles is proposed, involving multivariate analysis of covariance of the directly measured variables (e.g., total weight and gonadal weight), with body length being the covariate. Multivariate, univariate, and between-group tests can be used progressively if significant differences have ...

A multivariate analysis on the morphometrics of 7 Heterorhabditis species was conducted to review the status of the traditional morphometric characterization methods for differentiating species of these nematodes. Results from this study showed consistency in the selection of morphometric characters for discriminating among males and infective ...
