ClustGeo: an R package for hierarchical clustering with spatial constraints
Marie Chavent, Vanessa Kuentz-Simonet, Amaury Labenne +1
In this paper, we propose a Ward-like hierarchical clustering algorithm including spatial/geographical constraints. Two dissimilarity matrices and are inputted, along w…
Multivariate Analysis of Mixed Data: The R Package PCAmixdata
Marie Chavent, Vanessa Kuentz-Simonet, Amaury Labenne +1
Mixed data arise when observations are described by a mixture of numerical and categorical variables. The R package PCAmixdata extends to this type of data standard multivariate an…
Orthogonal rotation in PCAMIX
M. Chavent, K. Vanessa, J. Saracco
Kiers (1991) considered the orthogonal rotation in PCAMIX, a principal component method for a mixture of qualitative and quantitative variables. PCAMIX includes the ordinary princi…
ClustOfVar: An R Package for the Clustering of Variables
M. Chavent, V. Kuentz, B. Liquet +1
Clustering of variables is as a way to arrange variables into homogeneous clusters, i.e., groups of variables which are strongly related to each other and thus bring the same infor…
On central tendency and dispersion measures for intervals and hypercubes
Marie Chavent, Jérôme Saracco
The uncertainty or the variability of the data may be treated by considering, rather than a single value for each data, the interval of values in which it may fall. This paper stud…
