Compute heterophilicity
Similar to dyadicity, heterophilicity is the ratio between the actual number of mixed label edges and the expected number of mixed label edges. In this exercise, you will compute the network's heterophilicity.
For the expected number of mixed edges, use the formula \(n_ {NC}\cdot n_ {C}\cdot p\) where \(n_ {NC}\) is the number of non-churners, \(n_ {C}\) is the number of churners and p is the connectance.
You can use the variables NonChurnNodes, ChurnNodes, connectance, and MixedEdges.
