Using multivariate factor analysis to characterize the unbranched fatty acid profile in bovine rumen fluid
(Univ Antioquia, Fac Ciencias Agrarias, 2019-07-01)
Background:Multivariate factor analysis (MFA) could be used for analyzing the complex pattern of correlations among fatty acids (FAs) in the rumen. Objective:To investigate the potential use of MFA to extract information ...
The use of a multivariate statistical procedure in analysing the germination process of two bean cultivars, compared with a univariate approach
(2011)
Several studies on plant physiology are aimed at describing or assessing seed germination processes under laboratory conditions. With respect to seed germination of crop species, some statistical complexities have been ...
Relationship between reproductive and productive traits in Holstein cattle using multivariate analysis
(Wiley-Blackwell, 2020-04-17)
Multivariate procedures are used for the extraction of variables from the correlation matrix of phenotypes in order to identify those traits that explain the largest proportion of phenotypic variation and to evaluate the ...
Uncommon multivariate statistical methods for environmental studies: A review
(Elsevier, 2015-05)
In this paper we describe the characteristics and the applications of the multivariate methods for spectroscopic and chromatographic techniques independent component analysis (ICA) and two-dimensional correlation spectroscopy ...
Use of Bayesian Methods for Multivariate Bioequivalence Measures
(TAYLOR & FRANCIS INCNEW YORK, 2009)
In this paper, we introduce a Bayesian analysis for bioequivalence data assuming multivariate pharmacokinetic measures. With the introduction of correlation parameters between the pharmacokinetic measures or between the ...
A multivariate survival model induced by discrete frailty
(Taylor & Francis Inc, 2020-08-11)
Frailty models are generally used to model heterogeneity and dependence between individuals. The distribution of the frailty variable is often assumed to be continuous. However, there are situations where a discretely-distributed ...
Multivariate Outliers
(Springer Verlag Berlín, 2011)
In the statistical analysis of data one often is confronted with observations that appear to be inconsistent with the remainder of that set of data (Barnett and Lewis, 1994). Although such observations (the outliers) have ...
