QUADRATIC ASSIGNMENT PROCEDURE  Scramble the network by permuting the actors (randomly re-label the nodes), i.e. the actual network does not change, however, the position each node takes does.  Re-calculate the test-static on the permuted networks and compare it with test-statistic on the unscrambled network. Network structure is ‘controlled’ for. Keeps dependencies.
