文摘

Cohesive subgroups, core-periphery and hierarchical networks are studied. Seven actor non-response treatments are developed and applied to valued networks. The known blockmodel and the blockmodels for the treated networks are compared. Ignoring the problem of non-respondents is completely inappropriate. The median of k-nearest neighbours based on incoming ties performs the best.
