Analysis of the influence of a network on the values of its nodes : the use of spatial indexes.

Résumé

A growing number of data are modeled by a graph that can sometimes be weighted: social network, biological network... In many situations, additional informations are provided with these relational data, related to each node of the graph: this can be a membership to a given social group (for social networks) or to a given proteins family (for protein interactions network). In this case, a important question is to understand if the value of this additional variable is influenced by the network. This paper presents exploratory tools to address this question that are based on tests coming from the field of spatial statistic. The use of these tests is illustrated on several examples, all coming from the social network framework.
