Centrality Measures in Interval-Weighted Networks
Hélder Alves, Paula Brito, Pedro Campos
Centrality measures are used in network science to evaluate the centrality of vertices or the position they occupy in a network. There are a large number of centrality measures acc…
Discriminant Analysis of Distributional Data viaFractional Programming
S. Dias, P. Brito, P. Amaral
We address classification of distributional data, where units are described by histogram or interval-valued variables. The proposed approach uses a linear discriminant function whe…
Factor Analysis of Interval Data
Paula Cheira, Paula Brito, A. Pedro Duarte Silva
This paper presents a factor analysis model for symbolic data, focusing on the particular case of interval-valued variables. The proposed method describes the correlation structure…
Distribution and Symmetric Distribution Regression Model for Interval-Valued Variables
Sónia Dias, Paula Brito
Symbolic Data Analysis works with variables for which each unit or class of units takes a finite set of values/categories, an interval or a distribution (an histogram, for instance…
Distribution and Symmetric Distribution Regression Model for Histogram-Valued Variables
Sónia Dias, Paula Brito
Histogram-valued variables are a particular kind of variables studied in Symbolic Data Analysis where to each entity under analysis corresponds a distribution that may be represent…
