An Overall Centrality Measure : The Case of U . S Stock Market

چکیده
In social network analysis, there have various traditional centrality measures that commonly used to determine the relative significance of a node in the network. They determined the centrality of nodes with different definitions. In this paper we propose an overall centrality measure which is an optimal linear combination of the traditional measures where the optimality criterion is similar to that in principal component analysis. This measure can be used to summarize the characterization of traditional measures determined on a node in the network. A study on the NYSE 100 stocks will illustrate its advantages.
