Implicit blockmodeling
 | This article provides insufficient context for those unfamiliar with the subject. (September 2021) |
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 perform worse than valued and homogeneity blockmodeling with a pre-specified blockmodel.[1]
