A k-dissimilarity D on a finite set X, |X| ≥ k, is a map from the set of size k subsets of X to the real numbers. Such … (<CitationRef CitationID="CR19">2004</CitationRef>) recently posed the following question: Given an arbitrary k-dissimilarity, how … ≥ 3 a k-dissimilarity on a set X arises from a tree if and only if its restriction to every 2 k-element subset of X arises …

This paper studies the inequality in the distribution of social interaction profiles among individuals. An interaction profile assigns the probabilities that one individual has to interact with well defined social groups and it can be inferred, for instance, from observations of social ties...

Many studies explore when and how young people make sexual choices but few empirical investigations link their sexual motivations with their inner conceptions about their sexual identities. We used multidimensional scaling (MDS) analysis to connect young adult participants’ (N = 128)...

In … this paper, we evaluate four dissimilarity measures for product recommendation using an online survey. In this survey, we …

We discuss a unified approach to the description and explanation of life course patterns represented as sequences of states observed in discrete time. In particular, we study life course data collected as part of the Dutch Fertility and Family Surveys (FFS) to learn about the family formation...

We conceptualize the notion of dissimilarity making use of reasonable transformations of the groups' distributions … substantial differences underlying the concept of dissimilarity when applied to ordered or to permutable classes. In both settings …

We consider the problem of the visualization of life courses represented as sequences. We describe the state of the art and introduce new plots which improve the graphical display of sequences unveiling their most salient features. Our proposal is based upon the application of smoothing...
