Sensitivity and elasticity analyses for the simulated spread of rabies and canine distemper virus (CDV) in San Clemente Island foxes. Sensitivity (s) is the proportional difference in output between simulations with new parameter value and simulations with baseline parameter value. Elasticity (e) is the proportional difference in output value divided by the proportional difference in parameter value. Bolded values indicate parameters with |e| ≥ 0.5.
