Workshop on Statistical Analysis of Networks

Synopsis

Analysis of networks from a statistical perspective is evolving rapidly in recent years. The aim of this workshop is to gather researchers working in this area to examine latest developments in the field, exchange ideas and look beyond the state-of-the-art. This workshop is funded by EPSRC and CRiSMLink opens in a new window.
