Estimating Parameters of a Probabilistic Heterogeneous Block Model via the EM Algorithm
We introduce a semiparametric block model for graphs, where the within- and between-cluster edge probabilities are not constants within the blocks but are described by logistic type models, reminiscent of the 50-year-old Rasch model and the newly introduced α-β models. Our purpose is to give a parti...
