Última Multivariate analysis of stable isotope data in the traceability process for birds - doi: 10.4025/actascianimsci.v34i4.13434 Animal Sciences Sartori, Maria Márcia Pereira; Denadai, Juliana Célia; Garcia, Amélia Maria Lima; Carrijo, Alfredo Sampaio; Ducatti, Carlos.  Isotope analysis has proved to be an extremely important tool in the traceability process; however, statistical analyses of the results show discrepancies, as the data depend on and originate from several chemical elements such as carbon, hydrogen, oxygen, nitrogen and sulfur (CHONS). In order to establish the proper analysis of traceability data for birds using the stable isotope technique and evaluate the need for a combined analysis of the variables, data for carbon-13 and nitrogen-15 were used from eggs (albumen + yolk) of laying hens and the pectoral muscle of broilers, which were subjected to univariate statistical analysis (ANOVA and complemented with Tukey’s test) and multivariate statistical analysis (MANOVA and Discriminant Analysis). The data... Tipo: Info:eu-repo/semantics/article Palavras-chave: 5.04.00.00-2 ANOVA; Discriminant analysis; Carbon-13; MANOVA; Nitrogen-15. Ano: 2012 URL: http://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/13434 Analyzing distances AgEcon Fenty, Justin. Gower and Krzanowski (1999) described the analysis of a multivariate dataset that violated the assumptions of normality for multivariate analysis of variance. They developed a method comprising two aspects: a graphical representation of the points in a fewer number of dimensions, known as principal coordinate analysis; and a technique similar to MANOVA except that it was based on partitioning the distances between subjects, rather than sums of squares, and did not assume that the data followed any particular distribution. This article summarizes both aspects of their analysis and describes the Stata pco and aod commands, which perform principal coordinate analysis and analysis of distance.
