Implicit blockmodeling
Implicit blockmodeling is an approach in blockmodeling, similar to a valued and homogeneity blockmodeling, where initially an additional normalization is used and then while specifying the parameter of the relevant link is replaced by the block maximum[1]
This approach was first proposed by Batagelj and Ferligoj in 2000,[2]: 16–17 and developed by Aleš Žiberna in 2007/08[3][4].
Comparing with homogeneity, the implicit blockmodeling will perform similarly with max-regular equivalence, but slightly worse in other settings. It will performe worse than valued and homogeneity blockmodeling with a pre-specified blockmodel.[1]
