Table 2 Tail exponent of the degree distribution per attribute of model class \(\mathscr {P}(\alpha , \mu , f)\) for different network sizes N and asymptotically (\(N\rightarrow \infty\)), where \(\alpha =1\), \(\mu =(0.7,0.2,\) 0.1), \(f(a,a)=0.8\), \(f(a,a')=0.1\), \(a\ne a'\)\(=1,2,3\) and \(m = 1\)
