what are self loop probabilities in graph why should self loop probabilities be included why are self loop probabilities included why is the self loop in modularity why should self loop probabilities be included in q which is the purpose of the modularity function? why are self loop probabilities not included when you use a modularity function, why are probabilities of self-loops included why are self loops not included in the q function why are probabilities of self loop included in the q function? why are self loop probabilities excluded why are probabilities for self loops included? what is r module what are self loop probabilities why are self loop probabilities not included? why are self loop probabilities included in modularity which function is the q formula why are self loop probabilities included in r why is self loops included in the r formula? why do self loop probabilities need to be included in a graph?
