  • Non-response in social networks : the impact of different non-response treatments on the stability of blockmodels
    Žnidaršič, Anja, 1981- ; Ferligoj, Anuška ; Doreian, Patrick
    Discerning the essential structure of social networks is a major task. Yet, social network data usually contain different types of errors, including missing data that can wreak havoc during data ... analyses. Blockmodeling is one technique for delineating network structure. While we know little about its vulnerability to missing data problems, it is reasonable to expect that it is vulnerable given its positional nature. We focus on actor non-response and treatments for this. We examine their impacts on blockmodeling results using simulated and real networks. A set of "known" networks are used, errors due toactor non-response are introduced and are then treated in different ways. Blockmodels are fitted to these treated networks and compared to those for theknown networks. The outcome indicators are the correspondence of both position memberships and identified blockmodel structures. Both the amount and type of non-response, and considered treatments, have an impact on delineated blockmodel structures
