Multilevel modelling of double-sampled clustered social networks with individual-level data on between-cluster ties
Fiona Steele, Justin Weltz, Eleanor A. Power +1
We consider the analysis of dyadic network data on ties between individuals in different clusters where the presence of a directed tie is reported by each individual in a dyad and…
Social Network Structure, Wealth, and Wealth Inequality Across Cultures

Most linear experimental design problems assume homogeneous variance although heteroskedastic noise is present in many realistic settings. Let a learner have access to a finite set…
