Multivariate Analysis (MVA) Data Analysis: Simple and Multiple Symmetric and Non-symmetric Correspondence Analysis
No full textThe Analysis of Sensory and Chemical-Physical Variables via Multivariate Additive PLS Splines
No full textWhen the information given by a panel of judges on wine sensory characteristics is resumed in a threeway
table, Y, and the objective is to extract knowledge from a chemical data-set, X, which has a predictive
power for wine sensorial variables, the study of the relationships between chemical–physical variables
and sensorial data sets is really complex. In this paper after resuming the information in Y, we propose
to consider multivariate additive partial least squares via splines, recently presented in literature, to predict
Y by X
Three-way Association Measure Decompositions: the Delta Index
No full textIn this paper we describe a general framework to decompose three-way association
measures for contingency tables, in particular symmetric and non-symmetric measures
will be discussed, like Pearson’s index, Marcotorchino’s index, whose special case is the
Gray–Williams index, and a new non-symmetric one will be proposed, called the Delta
index. After showing the orthogonal decomposition of these indices, practical examples
illustrating the different decompositions will be give
