Many trait measurements are size-dependent, and while we often divide these traits by size before fitting statistical models to control for the effect of size, this approach does not account for allometry and the intermediate outcome problem. We describe these problems and outline potential solutions.
许多性状测量都与大小有关,尽管我们通常在拟合统计模型以控制大小的影响之前将这些性状按大小划分,但这种方法并没有考虑到异速生长和中间结果问题。我们描述了这些问题,并概述了潜在的解决方案。
