Canonical Variate Analysis and Related Methods with Longitudinal Data
Canonical variate analysis (CVA) is a widely used method for analyzing group structure in multivariate data. It is mathematically equivalent to a one-way multivariate analysis of variance and often goes by the name of canonical discriminant analysis. Change over time is a central feature of many …

Distribution of Foraminifera and Pollen in Coastal Depositional Environments of the Southern Delmarva Peninsula, Virginia, U.S.A.
… from the coastal zone were subjected to canonical variate analysis which discriminated 83% of the stations in 19 groups. These groups were clustered into two internally overlapping sets which represented the inside and outside of the inlet.</p> <p>Twenty-two pollen types were found in …

Development of Molecular and Morphological Resources for Identification and Monitoring of Freshwater Mussel Species in the Genera Fusconaia and Pleurobema in the Green River, Kentucky
… differences among these species. Using Canonical Variate Analysis, I found discernable morphological differences between the investigated species of Fusconaia and Pleurobema. The two Fusconaia species were morphologically different from the Pleurobema species. However, the Canonical …

Morphometric Characterization of a <i>Mercenaria</i> spp. (Bivalvia) Hybrid Zone: Paleontological and Evolutionary Implications
… hybrid zone using Bookstein coordinates and multivariate methods to answer two questions: (1) can hybrid <i>Mercenaria</i> spp. individuals be identified based on morphology alone, and (2) would a <i>Mercenaria</i> spp. hybrid zone be recognizable in the fossil record? Multivariate statistical …

The Sediment Sources of Atlantic Shore Beaches between Montauk Point and Democrat Point, Long Island New York USA
… three environments were subjected to S.E.M. analysis using a checklist approach. Qualitative results comparing individual quartz grain surface feature variability with transport distance west of Montauk Point divided the south shore into three sections largely on the basis of mechanically …

Changes in benthic marine macrophyte community structure in the Strait of Georgia: long-term and grazing responses
… 1992 was compared to that in the 1970's. A multivariate approach was taken for the analyses, using principal component analysis, canonical variate analysis (CVA), and a modification of CVA including depth as an environmental variable. Several macrophyte associations were consistently found by the …

The construction of a partial least squares biplot
In multivariate analysis, data matrices are often very large, which sometimes makes it difficult to describe their structure and to make a visual inspection of the relationship between their respective rows (samples) and columns (variables). For this reason, biplots, the joint graphical display of …

Understanding methods for internal and external preference mapping and clustering in sensory analysis
… must answer before choosing a method of analysis: 1) are the different methods providing the same interpretation, co-ordinate values and object orientation; and 2) which method and program should be used with the data provided? This research used data from paint, milk and fragrance …

Studies on the biology of Plagiorchis elegans (Rudolphi, 1802), (Trematoda: Digenea) in its mammalian and molluscan hosts
… of LACA mice are compared statistically using canonical variate analysis. The only reliable anatomical criteria for distinguishing species of Plagiorchis are: 1. the relative sizes of the suckers and pharynx. 2. the presence or absence of a seminal receptacle, vas deferens and common genital …

Geographic variation in the phenotype of an African horseshoe bat species, Rhinolophus damarensis, (Chiroptera: Rhinolophidae)
… populations and lineages of R. damarensis. Multivariate Linear Regressions (MLV) and Linear models (LM) on the basal parts of bacula revealed significant differences between the southern and northern lineages of R. damarenis. The bacula of the two lineages of R. damarensis appear to have …
