In this thesis I develop multivariate statistical and network methods for the study of complex systems. In particular, I focus my analysis on the study of bipartite complex networks and their applications to (i) economics to understand the contagion effect between sovereign and financial institutions, (ii) insurance surveillance to uncover fraudsters and (iii) social science to study the effect of the politics of REF on research excellence of universities in the UK.
In questa tesi sviluppo metodi statistici multivariati e di rete per lo studio di sistemi complessi. In particolare, focalizzo la mia analisi sullo studio di reti complesse bipartite e le loro applicazioni a (i) l'economia, per capire l'effetto di contagio tra istituti finanziari e stati sovrani, (ii) la sorveglianza nelle assicurazioni, per individuare comportamenti fraudolenti, e (iii) le scienze sociali, per studiare l'effetto delle politiche del REF sulle eccellenze nella ricerca delle università in UK.

Abstract
In this thesis I develop multivariate statistical and network methods for the study of complex systems. In particular, I focus my analysis on the study of bipartite complex networks and their applications to (i) economics to understand the contagion effect between sovereign and financial institutions, (ii) insurance surveillance to uncover fraudsters and (iii) social science to study the effect of the politics of REF on research excellence of universities in the UK.File | Dimensione | Formato | |
