Boxplots of the estimation error of the degree distribution per attribute: Wikipedia (N2V-2 and -4: \(w_{ij} = 0.75\) if nodes have equal attributes and 1 otherwise), APS (N2V-2 and -4: \(w_{ij} = 0.25\) if nodes have equal attributes and 1 otherwise). N2V-3 and -4, \(\theta =10^{-3}\), \(\gamma =\beta =1\). The sample size for each sampling method is 0.2N
