The HJ biplot is a multivariate analysis technique that allows us to represent both individuals and variables in space of reduced dimensions. To adapt this approach massive datasets, it necessary implement new techniques are capable reducing the dimensionality data improving interpretation. Because this, we propose modern obtaining called elastic net biplot, which applies penalty improve interp...

In this paper Non-Symmetric Correspondence Analysis (NSCA, Lauro & D'Ambra, 1984; D'Ambra & Lauro, 1989, 1992) is proposed as an useful technique for evaluating contingency table with a dependence structure, in particular within the context of comparing market share di erences. Technical aspects of the method are discussed with a view towards application, giving special attention to the biplot ...

This article presents a new way of dealing with the self-organizing map methods to visualize by an original way qualitative data or histogram vectors as we can find on the Internet e.g. after the pre-processing of plain text documents. The main difference with other known methods is the nature of the processed matrix: a contingency table. By adding constraints during the learning of a mixture o...

This paper presents the R package CAvariants (Lombardo and Beh, 2017). The package performs six variants of correspondence analysis on a two-way contingency table. The main function that shares the same name as the package – CAvariants – allows the user to choose (via a series of input parameters) from six different correspondence analysis procedures. These include the classical approach to (sy...

Fusarium wilt (Fusarium udum Butler) is an important biotic constraint to pigeonpea (Cajanus cajan L.) production worldwide. Breeding for fusarium wilt resistance continues to be an integral part of genetic improvement of pigeonpea. Therefore, the study was aimed at identifying and validating resistant genotypes to fusarium wilt and determining the magnitude of genotype × environment (G × E) in...

The common bean is the most important grain legume for direct human consumption in the world and BCMV is one of the world's most serious bean diseases that can reduce yield and quality of harvested product. To determine the best tolerance index to BCMV and recognize tolerant genotypes, 2 experiments were conducted in field conditions. Twenty five common bean genotypes were sown in 2 separate RC...
