Particular interest is in roles as defined by local network connectivity patterns, identified using the ego-networks extracted from the network. A mixture of exponential-family random graph models (ERGM) is developed for these ego-networks to cluster the nodes into roles. We refer to this model as the ego-ERGM. An expectation-maximization algorithm is developed to infer the unobserved cluster assignments and to estimate the mixture model parameters using a maximum pseudo-likelihood approximation. We demonstrate the flexibility and utility of the method using examples of simulated and real networks.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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","url":"https://tandf.figshare.com/articles/dataset/Role_Analysis_in_Networks_Using_Mixtures_of_Exponential_Random_Graph_Models/1056514","contentUrl":null,"metadataVersion":3,"schemaVersion":"http://datacite.org/schema/kernel-4","source":"mds","isActive":true,"state":"findable","reason":null,"viewCount":0,"viewsOverTime":[],"downloadCount":0,"downloadsOverTime":[],"referenceCount":0,"citationCount":0,"citationsOverTime":[],"partCount":0,"partOfCount":0,"versionCount":0,"versionOfCount":0,"created":"2014-06-13T15:13:26.000Z","registered":"2014-06-13T15:13:27.000Z","published":"2015","updated":"2020-09-04T22:47:54.000Z"},"relationships":{"client":{"data":{"id":"figshare.ars","type":"clients"}},"provider":{"data":{"id":"otjm","type":"providers"}},"media":{"data":{"id":"10.6084/m9.figshare.1056514","type":"media"}},"references":{"data":[]},"citations":{"data":[]},"parts":{"data":[]},"partOf":{"data":[]},"versions":{"data":[]},"versionOf":{"data":[]}}}}
