The Sparse Latent Position Model for nonnegative weighted networks
Riccardo Rastelli
This paper introduces a new methodology to analyse bipartite and unipartite networks with nonnegative edge values. The proposed approach combines and adapts a number of ideas from…
Discussion of the article "Bayesian cluster analysis: point estimation and credible balls" by Wade and Ghahramani
Nial Friel, Riccardo Rastelli
We present a discussion of the paper "Bayesian cluster analysis: point estimation and credible balls" by Wade and Ghahramani. We believe that this paper contributes substantially t…
Computationally efficient inference for latent position network models
Riccardo Rastelli, Florian Maire, Nial Friel
Latent position models are widely used for the analysis of networks in a variety of research fields. In fact, these models possess a number of desirable theoretical properties, and…
A dynamic network model to measure exposure diversification in the Austrian interbank market
Juraj Hledik, Riccardo Rastelli
We propose a statistical model for weighted temporal networks capable of measuring the level of heterogeneity in a financial system. Our model focuses on the level of diversificati…
