Graphical models with marginals in the exponential family
Luis E. Nieto-Barajas, Simón Lunagómez
Graphical models encode conditional independence statements of a multivariate distribution via a graph. Traditionally, the marginal distributions in a graphical model are assumed t…
Bayesian nonparametric modeling of heterogeneous populations of networks
Francesco Barile, Simón Lunagómez, Bernardo Nipoti
The increasing availability of multiple network data has highlighted the need for statistical models for heterogeneous populations of networks. A convenient framework makes use of…
Modelling Populations of Interaction Networks via Distance Metrics
George Bolt, Simón Lunagómez, Christopher Nemeth
Network data arises through observation of relational information between a collection of entities. Recent work in the literature has independently considered when (i) one observes…
Distances for Comparing Multisets and Sequences
George Bolt, Simón Lunagómez, Christopher Nemeth
Measuring the distance between data points is fundamental to many statistical techniques, such as dimension reduction or clustering algorithms. However, improvements in data collec…
