Abstract
de Jager et al. (Reports, 24 June 2011, p. 1551) concluded that mussels Lévy walk. We confronted a larger model set with these data and found that mussels do not Lévy walk: Their movement is best described by a composite Brownian walk. This shows how model selection based on an impoverished set of candidate models can lead to incorrect inferences.
摘要
德雅热等人（报告，2011 年 6 月 24 日，第 1551 页）得出结论说贻贝采用 Lévy 漫步。我们用这些数据来检验一个更大的模型集，发现贻贝并非采用 Lévy 漫步：它们的运动最好用一个复合布朗漫步来描述。这表明，仅基于一套有限的候选模型进行模型选择，可能会导致错误的推断。
