Exercise

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.

Instructions
100 XP
  • Compute the expected number of mixed edges and assign it to the variable ExpectedHet.
  • Compute the heterophilicity by dividing the actual number of mixed edges with the expected number of mixed edges. Call this variable Het.
  • Is the network heterophilic? Inspect Het to find out.
