Multivariate techniques in the analysis of carcass traits of Morada Nova breed sheep Ciência Rural
Guedes,Déborah Galvão Peixôto; Ribeiro,Maria Norma; Carvalho,Francisco Fernando Ramos de.
ABSTRACT: This study aimed to use multivariate techniques of principal component analysis and canonical discriminant analysis in a data set from Morada Nova sheep carcass to reduce the dimensions of the original data set, identify variables with the best discriminatory power among the treatments, and quantify the association between biometric and performance traits. The principal components obtained were efficient in reducing the total variation accumulated in 19 original variables correlated to five linear combinations, which explained 80% of the total variation present in the original variables. The first two principal components together accounted for 56.12% of the total variation of the evaluated variables. Eight variables were selected using the...
