  16. Foulger notes that one might test the interaction directly but ought
  17. to be aware of its form.
  18.  
  19. Basically, if an interaction is hypothesized, then one ought to test a
  20. multiplicative model since the equation with interaction can always be
  21. re-written as a multiplicative one between linear transposes of the
  22. original variables.
