摘要：
This report describes a test for stability in a predator-prey system. The test is based on a parametric bootstrap applied under a model in which the predator-prey dynamics are log-linear. The test is illustrated using two published data sets. Some simulation results are presented showing that the test performs reasonably well when the predator-prey dynamics are nonlinear at the logarithmic scale.
