Garrick T. Skalski and James F. Gilliam. 2001. Functional responses with predator interference: viable alternatives to the Holling Type II model . Ecology 82:3083-3092.

Appendix 2: Test statistics, P values, and inferences for hypothesis tests involving the three alternative predator-dependent models. The hypothesis tests for distinguishing among the alternative predator-dependent models are of the form Hi: fi is the better model vs. Hj: fj is the better model (H2 = Holling Type II model, BD = Beddington-DeAngelis model, CM = Crowley-Martin model, HV = Hassell-Varley model).
