Jiang等人（JABES 12:177-194, 2007）提出了鱼类标签返回数据的模型。他们检查模型是否参数冗余，但需要借助于数值方法，因为符号方法有时被发现难以处理。此外，它们的结果仅适用于指定年数的标记数据和年龄类别。这里我们将展示如何使用符号方法，以及结论如何适用于任意年份的标记数据和年龄类别。这篇文章在网上有补充资料。
Jiang et al. (JABES 12:177-194, 2007) present models for tag return data on fish. They examine whether the models are parameter redundant, but need to resort to numerical methods as symbolic methods were sometimes found to be intractable. Also, their results are only applicable for a specified number of years of tagging data and age-classes. Here we show how symbolic methods can in fact be used and also how conclusions apply to any number of years of tagging data and age-classes.This article has supplementary material online.
